With the breaking news that [mc_name name='Rep. John Boehner (R-OH)' chamber='house' mcid='B000589' ] is resigning as Speaker and stepping down from Congress at the end of next month, the House caucus is going to have to elect a new leader soon. Reading between the tea leaves, you have to imagine that [mc_name name='Rep. Kevin McCarthy (R-CA)' chamber='house' mcid='M001165' ] thinks he has this election in the bag.
If Republicans in the House quickly line up behind McCarthy as a replacement for Boehner, it will show that they have learned nothing. It will show that they have mistakenly concluded that Boehner, personally, was just an unjust victim of Two Minutes' Hate from the voters, because McCarthy is cut from exactly the same cloth. While he might not be as orange or cry as much, there is no chance that he would hold the line where Boehner has failed to do so.
One assumes that the coup that finally brought Boehner down would not have gone forward if McCarthy had not clearly signaled to Boehner in some way that it was coming, or that he did not have the rest of the leadership team behind him. And presumably McCarthy would not have given that signal if he didn't believe that he had the votes to win a quick replacement election.
Probably, the way this is supposed to play out, at least from the standpoint of leadership, is that Boehner will, as his last act, fall on his sword to negotiate a clean funding bill that prevents a shutdown and provides for a debt limit increase. He will rely mainly on Democrat support. McCarthy will be allowed to pretend that he is opposed to this plan, while he counts the votes to make sure enough liberal/swing district Republicans are on board to make sure it passes. And then when this is all over, Boehner will be the appointed scapegoat and McCarthy will count on having a couple years of goodwill from the Republican voting public to try to get the caucus in order again.
Here is the thing - ignore how McCarthy votes and acts on the funding bill, as that will likely be pre-ordained as a sideshow. Watch how the caucus votes on the leadership election and how quickly they move. If McCarthy immediately consolidates support and wins on the first or second vote, it will show that House members, by and large, have learned nothing. It will show that dumping Boehner was purely a PR strategy instead of a recognition that the direction he was taking the caucus was untenable.
If McCarthy breezes into power basically uncontested, he should start from day one with just as much skepticism from conservatives both in the caucus and in the voting booth as Boehner does. McCarthy has had his hand on the tiller in just as many bad decisions as Boehner has, and has been responsible for many of the erroneous whip counts that embarrassed Boehner in the first place.
If conservatives want new leadership in the House, McCarthy is clearly not the answer. He's just a PR strategy for nervous Republicans who are scared of their own base. But this time, the base is smart enough to see through the ruse.
