Sabato: How Midterms Do (and Do Not) Differ From Presidential Elections

[krazen1211]

McCaskill and Donnelly are both in big, big trouble and almost certainly toast if the GOP nominates solid candidates in those states. Heitkamp, Tester, Manchin and Brown are all vulnerable as well. If it's a good or neutral year and Rs run strong campaigns, Nelson, Baldwin and maybe one of Stabenow, King or Casey can be beaten too. But even if that's not the case, the six seats I mentioned before are going to be tough for Democrats to hold.

King should be on retirement watch.
