Yesterday Sen. Bob Casey of Pennsylvania—the conservative Democrat who beat Rick Santorum in 2006 by 18 motherfucking points—came out for marriage equality. Today Sen. Tom Carper of Delaware, also a Democrat, endorsed marriage equality. Says Andy at Towleroad:

Carper joins a list of Democratic Senators who have come out for marriage equality in the last week. Only seven remain who haven't declared their support. They are: Joe Donnelly (D-IN), Tim Johnson (D-SD), Heidi Heitkamp (D-ND), Mary Landrieu (D-LA), Joe Manchin (D-WV), Bill Nelson (D-FL), and Mark Pryor, (D-AR).

Hard to imagine any of the remaining Dem Senators coming around—but two days ago I would've said the same thing about Bob Casey. Here's hoping Casey pulls a similar 180 on abortion rights and comes out for a woman's right to choose.
