Friend: Experts at CNN are calling me and my friends Mark Kelly (AZ), Catherine Cortez Masto (NV) and Maggie Hassan (NH) the most vulnerable Senate Democrats up for reelection in the entire country – and Donald Trump is backing Republican candidates to try and defeat us.

Here’s why we need to fight back now: The GOP needs to flip only one seat to retake Senate control for Mitch McConnell, and they're coming after the four of us as top targets for defeat. Our races will be the most competitive races this election cycle – so with shady GOP super PACs already spending millions to crush our grassroots campaigns, we're running out of time to pull ahead and win.

We urgently need to raise $75,000 before tonight’s midnight deadline – but at this critical moment, we're falling short. Please, friend: Will you split a contribution of $5 or more now to help us hold onto our battleground seats and defend our Democratic Senate majority?

Here’s the truth, friend: If we lose a single one of these seats, we could lose our Senate majority – and any chance at combating climate change, securing voting rights and protecting reproductive freedom. A recent report from CNN said that “the Senate playing field just tipped toward Republicans” – so this could become reality unless we fight back now.

This is one of our most urgent and important deadlines yet, and we're asking for your grassroots support to get back on track to win. Trump and McConnell will do anything and spend any amount to force their way back into power – and we've got to stop them.

Please, before 11:59 p.m. tonight: Rush a contribution of $5 to split between me, Mark Kelly (AZ), Catherine Cortez Masto (NV) and Maggie Hassan (NH) to help us win our neck-and-neck races and defend our Democratic Senate majority.

Thank you,

Sen. Raphael Warnock
