The Senate GOP campaign arm, the Daily Beast reports, has severed financial ties to Roy Moore after four women allege in a Washington Post report that the Senate hopeful had improper contact with them while they were still teenagers.

Snapping shut the war purse was the right decision.

Other prominent conservative publications and more prominent politicians have called on Moore to drop out of the race. But setting aside the ethics to focus on finances, the dollars-and-cents political calculation bears out the NRSC decision to maroon Moore.

Every penny spent ahead of the Dec. 12 special Alabama Senate election is a penny not saved for the rest of the electoral map. Money for Moore automatically means less cash for vulnerable incumbents like Dean Heller of Arizona and hungry challengers like Kevin Nicholson of Wisconsin. The definition of a zero-sum game, spending for Moore atomically harms every other Republican.

And it wouldn’t just be isolated injuries. GOP strategists have all but conceded that the NRSC can’t go toe-to-toe with the DSCC down in Alabama. The Washington Post story was the biggest gift to underdog Democrat nominee, Doug Jones. Honestly, how could Republicans match that with mere spending?

Every dollar would be earmarked, fairly or unfairly, by Democrats as money spent to elect a pedophile. Expect the left to drop cash like drunken sailors chugging Everclear ahead of prohibition.

More than anything else though, if Moore is going to win, the judge will do it himself, without the party's help. The Republican establishment hasn’t signed a check for the southern populist yet and he has done well enough. He thrives on opposition, specifically the narrative of conservative martyrdom that brings with it money and victory.

Like President Trump, Moore has always promised to stick it to the man. That game plan has worked in his state-wide Supreme Court races and more recently the Senate primary. Without establishment cash, Moore now finds himself in a comfortable and familiar place — on his own. No matter how you look at it, that’s for the best.
