A lot of them are like the ABR crowd - live lfe with blinders on and keep marching to the same drum, even if it is not working.
There is another nasty dimension to this. Everyone is blithely assuming that Senator Mark Kirk (R-IL), who is recovering from a massive stroke, will be able to return to the Senate in 2013. The Senator’s recovery is underway, but bad things can happen and his recovery could go sideways. Illinois has a Democratic governor, and would replace Kirk with a Dem in a New York minute.
Bottom line: EVERY seat matters. We have no room for error, and must prepare for EVERY contingency.
