^Yeah, there are also Gardner and Collins, but (a) I expect Heller and Gardner to lose reelection, (b) Collins was always an exception to the rule, plus Maine isn't really that Democratic and (c) Heller's election was a fluke because Shelley Berkley was a godawful candidate. Even Gardner only won by less than 2 in a perfect storm for Republicans. It's much more difficult for a Republican (regardless of how moderate they are) to win a Senate race in a Democratic-leaning state than it is for a Republican to do the same in a reddish state, which is why the Republican advantage in the Senate only exists on paper.
If Jason Kander were a Republican and running against... say... Patty Murray, he'd lose by 15 points despite being a good candidate.
What does any of that have to do with Alabama?
