If I recall correctly, even Ryan was surprised about that.
The only reason the "Ryan Plan" passed was that it was on the table at the time that Boehner needed a plan (any plan) to use as a bludgeon to hit Harry Reid with in the Senate. Boehner wanted the House to pass SOMETHING just to say that they passed a budget bill.
Ryan's plan was the low-hanging fruit at the time. Right place, right time. That's all.

This makes no sense whatsoever.
And the fact that the House passed this bill was a good thing. Not a bad thing. Even if it were to be changed later in conference (as every bill is) the rudiments were there.
