John: Democrat Abby Finkenauer, the youngest woman to flip a House seat from red to blue, is challenging Sen. Chuck Grassley (R) for Iowa's Senate seat. Here's the latest:

FIRST, a top Iowa pollster suggested Sen. Grassley's polling numbers show "weakness" after data revealed he's facing a RECORD-HIGH disapproval rating! This is the Democrats' best opportunity yet to flip this Senate seat blue!

BUT THEN, the campaign arm of the Senate Republicans reported that they have more than $32 MILLION in the bank – a massive sum of money that Mitch McConnell's allies can use to protect Sen. Grassley and take back the Senate. 

NOW, Abby is falling short of the resources she needs to fight back and flip this seat blue ahead of her first end-of-month fundraising deadline. She still needs 972 more grassroots supporters to become Senate Majority Defenders TONIGHT to make up the gap!

Will you rush a contribution of $5 or more now to become a Senate Majority Defender? Every dollar you give ensures Abby has the resources to defeat Sen. Chuck Grassley in Iowa and expand the Democrats' majority in the Senate!
