One of the more interesting aspects of this fight centers around the battle between Eric Cantor and John Boehner for control of the Republican House.  If Cantor wins, it may drive the more moderate Republicans toward the Democrats.  But it doesn’t appear at this point that the Tea Party Republicans really care about reelection – and perhaps they don’t even care if Obama wins reelection.

Paul Krugman has an interesting take of the Republicans.

Let’s talk for a minute about what Republican leaders are rejecting.

President Obama has made it clear that he’s willing to sign on to a deficit-reduction deal that consists overwhelmingly of spending cuts, and includes draconian cuts in key social programs, up to and including a rise in the age of Medicare eligibility. These are extraordinary concessions. As The Times’s Nate Silver points out, the president has offered deals that are far to the right of what the average American voter prefers — in fact, if anything, they’re a bit to the right of what the average Republican voter prefers!

Yet Republicans are saying no. Indeed, they’re threatening to force a U.S. default, and create an economic crisis, unless they get a completely one-sided deal. And this was entirely predictable.

First of all, the modern G.O.P. fundamentally does not accept the legitimacy of a Democratic presidency — any Democratic presidency. We saw that under Bill Clinton, and we saw it again as soon as Mr. Obama took office.

As a result, Republicans are automatically against anything the president wants, even if they have supported similar proposals in the past. Mitt Romney’s health care plan became a tyrannical assault on American freedom when put in place by that man in the White House. And the same logic applies to the proposed debt deals.

Put it this way: If a Republican president had managed to extract the kind of concessions on Medicare and Social Security that Mr. Obama is offering, it would have been considered a conservative triumph. But when those concessions come attached to minor increases in revenue, and more important, when they come from a Democratic president, the proposals become unacceptable plans to tax the life out of the U.S. economy.

…

Which brings me to the culpability of those who are only now facing up to the G.O.P.’s craziness.

Here’s the point: those within the G.O.P. who had misgivings about the embrace of tax-cut fanaticism might have made a stronger stand if there had been any indication that such fanaticism came with a price, if outsiders had been willing to condemn those who took irresponsible positions.

But there has been no such price. Mr. Bush squandered the surplus of the late Clinton years, yet prominent pundits pretend that the two parties share equal blame for our debt problems. Paul Ryan, the chairman of the House Budget Committee, proposed a supposed deficit-reduction plan that included huge tax cuts for corporations and the wealthy, then received an award for fiscal responsibility.

So there has been no pressure on the G.O.P. to show any kind of responsibility, or even rationality — and sure enough, it has gone off the deep end. If you’re surprised, that means that you were part of the problem.

It was fun for a while to watch Boehner herding the Republican cats and watching the infighting, but now it is time for moderate Republicans to join the Democrats and show some common sense.
