You're seeing a party in crisis at the moment. You've got about 40 members of the GOP (this number is from Peter King R-NY) who are wagging the dog. Boehner isn't really in charge and can't bring them in line without losing his job as speaker in the process. Cruz seems bound and determined to make a name for himself as being the guy who defunded Obamacare. After years and years and years of negotiating against himself, Obama has finally decided that he's not going to respond to hostage taking anymore. To the extent Obama is to blame, it's because he's given in to these tactics previously and encouraged the GOP to do it again and again.
Stoked, you keep repeating that the people elected this house to do what it's doing now. That's only kind of true. Gerrymandering played a huge role in the party make-up of the house. Even though the House GOP outnumbers the Dems by 32 seats, the reality is that Democrats won an aggregated popular vote in house races by more than a million votes. In fact the discrepancy between popular vote and seat representation is the largest it's been in more than 60 years.

This is the most true statement out there. There Repubs don't know who/what they are. One republican wrote his own healthcare bill. Another hates it. One passed a flat tax, but is for gay marriage, so he isn't a "true" republican. One thinks that if you are raped, you won't get pregnant.
The leadership and organization of the Repub party is gone. It doesn't exist. Look at this country. It is in shambles. You can easily toss all the blame on the left, as they had full control for two years, the white house for the last 6 and the Senate for the last 8? 10?
Yet, no one does. The left is so organized, so in sync with each other, so united, they continue to win even though reality says that the right should be winning. Obama ran on lowering taxes the first time around. McCain ran on nothing.
Until the right actually figures out what they stand for, get united, all say the same message, that party is screwed and won't accomplish anything, because they don't know what they are trying to accomplish.
For example, here in Utah, Hatch's opponent in the primaries ran on this:
"Orrin Hatch has been in Washington too long."
He didn't say what Hatch was doing wrong, what was wrong in Washington, or what he would do if he were elected. All he said was "I should be elected because Hatch is too old". The republican party is pathetic right now.
