What's at stake for Kamala Harris in her VP acceptance speech tonight.

"Harris will begin working to change this dynamic with her Wednesday address at the virtual Democratic National Convention, in what will easily be the biggest political speech of her career. Her speech offers a prime opportunity to try to sway the minds of young liberal voters with doubts about Biden." (The Hill)

• What's happening: Tonight Kamala Harris will make her VP acceptance speech at 9pm Eastern at the virtual Democratic National Convention. She'll be followed by President Barack Obama.

• What's at stake: The media and pop culture figures will praise Harris' speech no matter what happens. (The first joint Biden-Harris interview was a glowing profile in People of all places! You can't imagine that with Trump-Pence.)

But tonight Harris has two contradictory tasks that show the deep split in the Democratic Party -- and how far out of touch they are with most Americans.

(1) Convince young Democrats and far-left progressives she agrees with them.

There's a major lack of enthusiasm for Joe Biden among Generation Z and Bernie Sanders' progressives -- even though the media never talks about it. It could mean big trouble for the Biden-Harris ticket on Election Day.

(2) Not terrify the rest of America with her incredibly far-left policies.

As the Washington Free Beacon puts it succinctly: Harris "supports the Green New Deal, Medicare for All, a mandatory 'assault weapon' buyback program, and a ban on fracking."

But you shouldn't expect to hear Democrats' true agenda at their convention, as Jim Geraghty at National Review explaine (check out his full commentary!): "A party that doesn’t usually overflow with respect for flyover country and red states suddenly speaks fondly of small-town America. Sunny optimism abounds. The American flag, sometimes considered jingoistic and a little gauche in some Democratic circles, is ubiquitous again."

• What else to know: Ahead of President Obama's speech tonight, check out this fascinating read about his relationship with Biden. Spoiler: Hillary Clinton is mentioned a lot too.

Like it's 2016 all over again, Hillary Clinton expects "I-told-you-so moment" in convention speech tonight.

"Call it Hillary Clinton’s I-told-you-so moment. The 2016 Democratic nominee will have an opportunity to address the nation Wednesday in a prime-time speech for the first time since she lost her bid for the White House in a stunning defeat to now-President Trump." (The Hill)

• What's happening: While Bill Clinton was relegated to a five-minute pre-recorded video, Hillary Clinton has been honored with a live speech immediately before Kamala Harris.

• What's at stake: Not much for America ... but a lot for Hillary Clinton, who just can't seem to surrender the spotlight.

This year, she's launched a podcast and said she'd like to serve in a future Biden-Harris Administration. Now she's got a primetime convention speech, too.

In comments to The Hill, Clinton "confidants and those who have worked for her" (interpret that as this is a news story and media angle that Clinton wants told) frame it as an "I-told-you-so moment."

In other words, Clinton is likely to make the 2016 case for her candidacy all over again. We expect Americans will be just as enthusiastic for it now as they were then.

• What else to know: Before Clinton tonight, the speaker line-up will also feature Elizabeth Warren and Nancy Pelosi. Check out the full schedule from the Democratic National Convention here.

There won't be changes to the U.S. Postal Service ahead of the 2020 election, but don't expect the left to give up now.

"Postmaster General Louis DeJoy said in a statement on Tuesday that he would halt operational changes and cost-cutting to the U.S. Postal Service until after the 2020 election to 'avoid even the appearance of any impact on election mail.'" (Axios)

• What's happening: In response to complete (and sudden) outrage from the left, the U.S. Postmaster General -- who runs the U.S. Postal Service -- said he'll stop all proposed changes until after the 2020 election.

That change matches what has been reported as the "emergency" legislation from the House Democrats (see more below!). But don't expect the left to give up the fight so easily.

• What's at stake: This presidential election will likely see an unprecedented spike in voting by mail. So ballot security and mail delivery are more important than ever.

The media and the Democrats would like to position themselves as the safeguards of democracy. But we suspect there are other factors at play:

(1) We predict that this issue may morph into Democrats claiming that they must challenge election counts across America after the presidential election -- throwing us into a Florida 2000 recount scenario, except in far more states.

Remember: Joe Biden has a team of 600 lawyers ready to go.

But we think that they'll need to make a public case first for why the presidential election should be dragged out in lawsuit after lawsuit after lawsuit. Creating a national panic over the U.S. Postal Service would probably fit that nicely.

(2) The left has had a difficult time re-writing vote-by-mail rules through the courts (remember: last month a Democratic super PAC dropped its challenge in Florida), so now they are the ones trying to "politicize" the U.S. Post Office.

Although the Democrats are dramatically calling the House back into session, their legislation just stops the Post Office from making any changes that weren't already in place on January 1, 2020. 

So they want the American people to believe that President Trump is (1) simultaneously "destroying" the postal service and (2) the solution is to roll back to previous Trump Administration policies from January.

It's almost like it's not about President Trump or his Administration at all!

• What else to know: We'll see this issue continue to develop this week. The Postmaster General will testify before a Republican-led Senate committee on Friday and a Democrat-led House committee next week.

Is this the reason AOC got her speaking spot at the Democratic National Convention?

"Biden's convention has so far seemed more intent in reaching out to moderates and disillusioned Republicans rather than the left wing of the party that he defeated in the primary. It's unclear whether Ocasio-Cortez would have spoken at all had Bernie Sanders not asked her to second his nomination." (POLITICO)

• What's happening: In a confusing moment for many viewers at home last night, Rep. Alexandria Ocasio-Cortez (AOC) used her 60-second speech at the Democratic National Convention as support for Bernie Sanders.

But that was an expected procedural move -- as all candidates with delegates to the convention required formal nomination -- even though it was jarring. It may also have been the only reason that AOC was asked to speak at all.

• What's at stake: The mainstream media doesn't want to report on the split in the Democratic Party. But left-wing outrage over AOC's limited role shows how deep it goes.

Despite talks of "unity" from both Joe Biden and Sanders, there's been serious disagreement among their supporters within the party. Just weeks before the convention, "key committee" members fought with each other in a private online meeting -- and it was so acrimonious, it made news media coverage.

AOC has repeatedly said she's voting for Biden, but she hasn't endorsed him. That could be bad news for the Biden-Harris ticket in November, though you'll never hear the media acknowledge it.
