We wanted to make sure you saw the news, John:

The Koch network has officially waded into our race -- pouring more than $100,000 in to prop up our opponent, Senator Thom Tillis.

This comes after multiple public polls show Tillis in a tough primary and losing to Cal in the general election. Not to mention, a slew of major election forecasters just rated our race a toss-up.

To be blunt: things are looking bad for Tillis and the Koch network is taking notice -- so they’re swooping in to try to save him.

We need to fight back and make sure voters learn the truth about Tillis’ weak leadership for North Carolina -- not the lies being spread by the Koch network. Donate $10 or more before next week’s end-of-month deadline to help us spread that message today.

You can be sure that the Koch network and Mitch McConnell’s dark money groups will keep writing their million-dollar checks to support Tillis.

But we can stand up to them -- so long as each and every person chips in right now to make it happen.

— Team Cal
