Can The Ryan Plan Pass The House?

Steven Taylor has doubts:

I am wondering if a majority of House Republicans are going to be willing to go on record for a plan that will end Medicare as we know it.  Yes, there are many in the Republican base, especially the Tea Party faction, that are currently quite passionate about the plan.  However, with the 2012 elections around the corner, how willing are individual members of the House to go home and campaign for reelection after having voted to utterly transform Medicare?  Worse, since even if the given member believed in the Ryan Plan they know that it will never pass the Senate (let alone survive the veto pen if it did).  As such:  why go home and risk the wrath of constituents over Medicare when the whole thing is a legislative dead end?
