I have a post up at Post Partisan today noting that the new Crossroads ad against Claire McCaskill that hits her on ACA -- but, I note, the substantive problems identified with "Obama - Claire" are all about Medicare cuts.
To flesh it out a bit...I looked through the web sites of the Republican Senate candidates (this is my group of the 16 candidates most likely to become United States Senators in this cycle) to see what they had to say on the issue. As expected, it's a popular talking point still during this election cycle; all but one had something about it (if George Allen does, I couldn't find it). Of those 15, only Linda Lingle of Hawaii wasn't clearly for repeal; she only had concerns about it. I should also add that "repeal and replace" has faded, with only two candidates holding that position. The rest were just for repeal.
Ah, but what did they think was wrong with Obamacare? Mostly, they didn't feel it was necessary to explain. About half didn't really say anything substantive at all. Of the rest, Medicare cuts were mentioned by three candidates; cost by two; the mandate by two, and at least one general complain that it's unconstitutional.
I guess one can make of that whatever one wants. Is ACA (thought to be) so unpopular that just mentioning it is enough? Are Medicare cuts the single most common complaint by Republican politicians about ACA? Is Medicare just one of several issues that Republicans think will work?
I believe that someone collected evidence of what was in the 2010 health care reform attack ads; anyone remember that?
