Our 24 targeted districts, featuring vulnerable Republicans who voted to repeal the Affordable Care Act. (Incumbents no longer seeking re-election are grayed out.)

One year ago today, House Republicans voted to repeal the Affordable Care Act, the culmination of their years-long crusade to strip health coverage from millions of Americans. But that act of wanton cruelty proved to be a double disaster for the GOP: Not only did their scheme go down to a humiliating defeat in the Senate, it ignited progressives with a furor we’ve never seen before.

That's not hyperbole—we have hard data to back up that claim. In just a little over 24 hours, the Daily Kos community donated an astounding $1 million to defeat the two dozen most vulnerable House Republicans who’d supported this monstrosity. That total ultimately climbed to more than $1.7 million, which you can see in the thermometer embedded in this post.

Oh, our previous first-day fundraising record? $17,000.

What made this explosion even more amazing, though, was the fact that we weren’t even raising for any actual candidates. Because it was so early in the election cycle, many of these at-risk GOP House members didn’t yet have Democratic challengers. So we asked our partners at ActBlue to dust off an old tool, what they call Democratic Nominee Funds. These are escrow funds that hold all donations until each state’s primary, then disburse any money raised to the winner of the Democratic nomination in each district.

To be honest, these funds had fallen into disuse because they never caught on—it had always seemed too difficult to get people excited about donating to a faceless escrow fund rather than a real, live candidate. But we were so hungry for a way to hit back against heartless House Republicans that we felt we had to give them a shot. The results speak for themselves.

But here’s another remarkable thing: Every single one of the 24 House districts we targeted a year ago now has at least one—and in many cases, more than one—credible Democratic candidate. And on top of that, five of of the Republican incumbents in these races have since declined to seek re-election:

District Republican District Republican AZ-02 OPEN (McSally) IL-06 Roskam, Peter CA-10 Denham, Jeff IL-13 Davis, Rodney CA-21 Valadao, David IL-14 Hultgren, Randy CA-25 Knight, Steve KS-03 Yoder, Kevin CA-39 OPEN (Royce) MI-11 OPEN (Trott) CA-45 Walters, Mimi MN-02 Lewis, Jason CA-48 Rohrabacher, Dana MN-03 Paulsen, Erik CA-49 OPEN (Issa) NE-02 Bacon, Don FL-25 Diaz-Balart, Mario NJ-11 OPEN (Frelinghuysen) FL-26 Curbelo, Carlos TX-07 Culberson, John IA-01 Blum, Rod TX-32 Sessions, Pete IA-03 Young, David VA-02 Taylor, Scott

Primaries have already taken place in Illinois, and ActBlue distributed over $212,000 to the Democratic nominees in the three races listed above. But you can still help out in all of the other districts—and they definitely need your help. Republicans may have lost last year’s battle over Obamacare, but they’re desperate not to lose this year’s fight for the House. And we know this community is still raring to win.

On this extraordinary anniversary, can you give $1 to help win each of these Republican seats—and take back the House this fall?
