MICHAEL BARONE: Dems retreat to coasts as GOP rules vast interior. “The Democrats’ Northeast and Pacific Coast bases are heavily populated, and the states where they’re leading in Senate races cast 136 electoral votes in 2008. But the states where Republicans are leading cast 274 electoral votes. These 2010 maps are quite a contrast with the maps you might have drawn just after the 2008 election.”

ANOTHER UPDATE: Linda Hirshman: White Women Dump The Dems. “Remember the PUMAs, whose motto was Party Unity My Ass? They were the supposedly angry white women (the horror) so pissed off by Hillary Clinton’s defeat they were going elect John McCain? The PUMAs were sort of lost in the pixie dust storm of the Obama election. I wonder if we declared them an endangered species too soon? There were glimpses that all might not be well with white women in the exit polls even then.” I think the misogynistic attacks on Sarah Palin don’t help.
