With 62 days to Election Day 2020, here's the news that you'll want to know:

(1) Democrats sue for last-minute voting rule changes in Pennsylvania, which Trump won by just 44K votes in 2016

(2) Democrats are scrambling as Biden drops in the polls

(3) presidential debate moderators announced today; see a run-down of all we know so far

(4) new poll: 77% of young voters in battleground states say they'll "definitely" vote

Pennsylvania voting rules still uncertain. The next step in the court case is September 8.

"Pennsylvania's highest court will take up another election-related lawsuit, it announced Tuesday, this one filed by the state Democratic Party amid a partisan fight over fixing glitches and gray areas in the battleground state's fledgling mail-in voting law. Briefs are due Sept. 8, the state Supreme Court said." (NBC Philadelphia)

• What's happening: With just over 60 days to go to Election Day 2020, the voting rules in a critical swing state -- Pennsylvania -- are still being decided in the courts. Legal briefs from both sides are due on September 8.

Democrats filed a lawsuit to weaken or replace existing voter rules, and it's now before the State Supreme Court. Among the changes that Democrats have sued for:

-- count mail-in ballots even if they're received after Election Day

-- count mail-in ballots even if they're returned without the secrecy envelope (a ballot is put into a secrecy envelope and then the secrecy envelope is put in a second envelope to mail it)

-- let voters change mail-in ballot errors before their ballots are discarded

-- accept mail-in ballots at "drop boxes" as well as satellite office locations, instead of just mailboxes

• What's at stake: The 2020 election. As you think about this lawsuit, remember that President Trump won Pennsylvania by just 44,000 votes in 2016!

(1) Americans must be able to vote in fair elections.

Assuming this case continues, it's astounding that Pennsylvania will not finalize its voting procedures for the 2020 presidential election until it's less than 60 days away.

(2) The presidential election could be decided by absentee or mail-in ballots.

So each change to a condition for receiving a ballot -- or each additional day a mail-in ballot will be accepted -- could change the final count. It could also marginally change campaigns' strategies to turn out the voters who support them.

(3) President Trump and Republicans are concerned by a potential increase in voter fraud from weakening ballot protections.

Here's a report from policy experts at the Heritage Foundation on the voter security concerns and what they recommend to run a safe, fair election.

(4) We think this is a preview of legal battles to come after the election.

Remember that the Biden campaign has a team of 600 lawyers ready to go, and the Republican National Committee doubled its legal budget to $20 million.

• What else to know: Last-minute legal battles aren't just an issue in Pennsylvania either.

Check out the most comprehensive list of COVID-related election lawsuits, maintained by law professor Justin Levitt. As of his last update on Monday, there are more than 225 cases in 43 states plus Puerto Rico and the District of Columbia.

Democrats trying to play catch-up as Biden drops in the polls, Trump surges in battleground states.

"Democratic presidential nominee Joe Biden’s lead over President Trump has narrowed 5 points to a 7-point lead since June, according to a USA Today-Suffolk poll. Fifty percent of registered voters polled said they plan to vote for Biden, compared to 43 percent who said they would vote for Trump. The 7 percentage point difference between the candidates marked a drop from the June results in which Biden led Trump by 12 points." (The Hill)

• What's happening: New polls out show the 2020 presidential race is tightening up as President Trump is rising in the polls. Nationally, Joe Biden has dropped 5 points. And in key battleground states: 

-- President Trump is ahead by an average 1 point in North Carolina

-- President Trump is ahead by an average 1.3 points in Georgia

-- there's a statistical tie between President Trump and Biden in Pennsylvania

• What's at stake: This could lead to a shake-up in campaign strategy in the final 60 days to Election Day.

The media and the left expected that Biden would cruise to victory. That helped Biden keep his progressive policy agenda under wraps, as he has done few public appearances and fewer media interviews.

But now Democrats are openly complaining about Biden's strategy, and the campaign seems to be scrambling in response.

-- Democrats were concerned about Biden's lack of travel (and now he's traveling)

-- Democrats were concerned about Biden's lack of media appearances (but we haven't seen much change on this front)

-- and President Trump went to Kenosha, Wisconsin to address the riots there ... so now Biden is headed to Kenosha tomorrow

Here's what we know about the presidential debates, including the just-announced debate moderators.

"The Commission on Presidential Debates on Wednesday announced moderators for the three presidential debates and one vice presidential debate, a lineup that includes Fox News anchor Chris Wallace and USA TODAY Washington Bureau Chief Susan Page." (USA Today)

• What's happening: Here's what we know so far about the upcoming presidential debates:

-- first presidential debate (Sept. 29): Chris Wallace (Fox News)

-- VP debate (Oct. 7): Susan Page (USA Today)

-- second presidential debate (Oct. 15): Steve Scully (CSPAN) for a townhall-style debate

-- third presidential debate (Oct. 22): Kristen Welker (NBC)

• What's at stake: The presidential debates are both a time-honored tradition and an important opportunity to compare the candidates directly.

Each debate this year will have a single moderator, rather than a panel. Single-moderator debates may have more opportunity for follow-up or clarifying questions from the moderator; much will depend on the moderator's style, though.

(1) President Trump is widely expected to have the advantage in the debates.

That's likely why his campaign asked for the debate schedule to be moved up and for a fourth presidential debate to be added. Neither the Biden campaign nor the nonpartisan debate commission were on board, though.

(2) Nancy Pelosi recommended that Biden skip the debates.

But Biden has, for now, rejected the idea. Let's hope it stays that way.

New poll: 77% of voters under 35 in battleground states say they'll "definitely" vote in November.

"Seventy-seven percent of youth voters in battleground states said that they 'definitely' plan to vote this November, according to an August poll conducted by NextGen America, a progressive group." (Daily Caller)

• What's happening: A new survey found that 77% of American voters under 35 in 13 battleground states said they'll "definitely" vote in November. That would be a significant jump from what usually happens, according to the Daily Caller: only 46% of voters under 30 voted in 2016.

• What's at stake: Every election cycle, someone promises that this will be the year of the youth vote. But it usually doesn't work out that way. Here's what we think this means for 2020:

(1) The electorate is unlikely to change substantially.

According to the Pew Research Center, in 2016, Baby Boomers and the generations older than them "accounted for 43% of eligible voters"; yet, "they cast 49% of the ballots."

Perhaps the higher intensity of voting interest, as this survey found, predicts a different outcome for 2020. But we will wait and see.

(2) It's often presumed that higher youth turnout favors the more liberal candidate. But Biden has struggled to connect with Generation Z, who are roughly voters ages 18 to 25. (The generation is formally defined as those born in 1996 and later.)

Although Gen Z is reportedly the "most pro-government, anti-Trump generation," that doesn't mean they're all in for Biden. Instead, they're more likely to be Sanders supporters.
