Who Doesn't Support Medicare Cuts? - From Dwyer and Walshe and Tapper - "One way or another, Barack Obama, Paul Ryan and Mitt Romney all have supported the $700 billion in cuts to Medicare spending now in place under the Affordable Care Act… But you wouldn't know that by listening to the current debate…. " Watching an ad from the Romney campaign today, "Voters might be left with the impression that Romney and Ryan have both opposed the cuts. The truth is that Ryan himself endorses them in his signature budget plan - the same plan Romney has said he would sign as president if it reached his desk." http://abcn.ws/OX3bRy

Tuesday Recap - The election may be more about big ideas now than it would have been without Paul Ryan. He may have given the GOP base an ideological shot in the arm. He may draw some more boldness out of Romney. The campaign may be "ecstatic," as we heard on GMA. http://abcn.ws/PhcMXi

But Ryan, the intellectual muscle of the House GOP, also gives Democrats the ability, for the first time, to directly tie the Romney ticket to Congress, which officially has the some of the lowest approval ratings for anything ever.

Yahoo!s Jeff Greenfield has these thoughts on Paul Ryan:

'For most observers, the question seems to be whether voters will reject Ryan's vision of government that has now been surgically grafted onto the Romney campaign. Will seniors will run screaming from a vision of health insurance vouchers? Will the inevitable slashing of programs will prove too draconian?

'My question is different: I wonder how long it will be before the focus of attention shifts back to Mitt Romney.

'As a general proposition, campaigns do not linger on the vice-presidential nominee. When they do, it's always meant very bad news for the ticket. Think of Spiro Agnew's foot-in-mouth disease; Tom Eagelton's medical history; the real-estate holdings of Geraldine Ferraro's husband; the unbearable lightness of Dan Quayle; Sarah Palin's reading list. There is no evidence that Paul Ryan would find himself the center of such unwelcome attention" - http://yhoo.it/Mv8Lxk
