Mary Cheney’s donation of $500 to Kelly Ayotte, New Hampshire’s Republican 2010 Senate candidate, is really just pocket change is the grand scheme of things. But Cheney has publicly spoken about how she supports same-sex marriage, and yet she’s donating to Ayotte (who wants to replace retiring GOP Sen. Judd Gregg), who does not. But Mary has a history of pulling for politicos who don’t support her right to marry, last year donating to Ohio Republican Rep. Rob Portman’s Senate campaign. Though last time around she was more generous; Portman got a full thousand.
