Paul Rahe tags the significance of the Ted Cruz speech.

 Hat tip to Glenn Reynolds.  The whole thing is worth a read, but this is the meat of it.

 "What the hearties in the House are doing — and what Ted Cruz is doing — is signaling to the discontented that there really is another way. They can vote Republican in 2014; and, if they do so big time, there will be a correction of course.

The leadership of the Republican Party hates this. Like Jeb Bush in early 2009, they want “to get beyond Reagan.” They want to surrender on immigration; they have designed a Republican healthcare bill that is little more than Romneycare writ large; and they desperately want to make nice with the Democrats. They do not really want a change of course. They merely want to take their turn as managers of the administrative entitlements state. They want to take advantage of discontent without having to commit themselves to a reduction in the size and scope of the government.

If they hate Ted Cruz — if behind the scenes they are feeding the media attacks on him — it is because he is threatening to throw a monkey wrench into the works. They hated the Tea Party. Initially, in 2009, they tried to dismiss it and get on with the process of surrendering to the Democrats on the healthcare question; and then, in August 2009, all hell broke loose in the town meetings, and Charles Grassley and the rest of them found that they had to back off. The Republican tide of 2010 kept them cornered, but the Tea Party folks did not have a plausible candidate to run for the nomination in 2012 and the whole thing subsided. Now the regulars are once again fully in charge — and along comes this maniac Cruz who threatens to revive the fervor of the Tea Party and force the Republicans to move in the direction of smaller government."

This explains a lot of the reaction we are seeing from both the Democrats and the Rinos.
