On the last point - I don’t think all conservatives are willing to allow, e.g., the country to go into default. The Tea Party? Yeah, they are. But I think the rest of the party realized that the Democrats would fold and played their hand, i.e. went all in, knowing Obama and the Democrats would fold. But you point is valid, as long as the tea party and their ilk know the Democrats will fold, they are going to win every single time.
Worst case scenario for the Republicans is, of course, that they lose their jobs/get voted out. So worst case scenario for them is not taxes go up. Worst case scenario for them is taxes go up and they get blamed by their constituents for that. But ultimately, worst case scenario for them is they lose their support.
Support can be broken down into two things: financial/campaign fund support, and voter support.
Since most of their financial support is Wall Street/Business, there’s a slight hint of a small glimmer of an opportunity from recent events: The Wall Street Journal has attacked them, some GOP Senators have been saying their business based supporters have been very vocal in telling them how pissed they are that the party seems to not care about the country defaulting and pissed at the utter ignorance shown by the Tea Party in proclaiming A: nah, the country won’t really default, and B: even if it does, it’s just no big deal, after all, look at all the other countries that only have a AA rating and they survive just fine. Recent comments on Minnesota NPR about this, with some businesses telling their Reps/Senators hey, get these loonies under control or we pull our support. Of course, the problem is that these same supporters need to somehow see the Democrats as a better investment, and the lack of unity and effective messaging and also general philosophy on that side is not seen as business friendly.
On the other side, the voters: how do you get the people voting them in to turn on them? Certainly, it has happened in the recent past, re: the loss of the Senate and a lot of House seats a few years ago. I think you can almost write off the loonies behind the Tea Party - many of them are complaining today that passage of the House bill yesterday was a betrayal! Sigh - these people are like arguing with someone who is convinced the moon landing was a government con game. And I’m not sure of the demographics - are there enough looney voters to give these extremists their seats, i.e. do they need some amount of “normal” votes too? I don’t know.
But the rest of the Republicans are the real problem, in my opinion. The reason they let the tea party dictate the rules is they fear that these guys might be strong enough to take them out in the primaries. They saw it happen to some of their colleagues. Somehow, the “normal” Republicans need to be convinced that they are more likely to lose voters than gain voters by going along with the Tea Party.
(And I have to run to a meeting, much to anyone’s relief who has read this far, LOL! So more later…)
