A quick look at the political scene in Washington tells me that this is probably the most inconsequential bunch of Senate elections in my lifetime. For one thing, I have no confidence that a GOP-controlled Congress (both Houses) would pursue anything remotely resembling a conservative agenda to begin with. Secondly, that jug-eared dope in the White House isn't going to put his name on any substantive legislation that comes out of a Republican Congress.
Not one dime's worth of difference.
