The National Republican Congressional Committee announced on Thursday that it raked in $33.7 million in the first quarter (about $5 million of which came from Mr. McCarthy). It pulled in $19.1 million in March alone—an odd-year fundraising record. And the National Republican Senatorial Committee, under Florida Sen. Rick Scott, had one of its healthiest Februarys in years, bringing in $6.4 million—despite a precipitous drop in corporate PAC donations. (It has yet to report quarterly numbers.) The numbers are even more striking because they shouldn’t be. Republican voters remain demoralized over losing the presidency, and some are furious that more GOP lawmakers didn’t dispute the results. The party has yet to figure out how it will manage Donald Trump, and the potential for damaging clashes with the former president—over recruitment, primaries and issues—remains high. The Democrat-media complex is working hard to brand the party as racist, insurrectionist and toxic for suburban or minority voters to support. And Democrats crushed Republicans in fundraising last year. So what gives? Here’s what the obits are missing: Joe Biden, Nancy Pelosi and Chuck Schumer. Nothing unifies the Republican Party more than the threat of an all-Democrat, progressives-gone-wild Washington. GOP fundraisers tell me their pitch to donors the past two months has been as simple as it has been effective: The only way to stop the left’s radical transformation of the country is to retake the House and Senate. That objective is bringing Republicans together and opening pocketbooks—and the more Mr. Biden pushes left, the bigger and more the checks. The unity is forming much faster than it did in 2009, the last time the Democrats took the presidency and both congressional chambers.
