The Bushes are completely cynical on the social issues. George H.W> gave lip-service to pro-life after 1980, but his wife made it clear he did it for political expedience. W. was pro-life but his wife and girls made itclear that for him it was political, too. They sent to the girls out some time again to pronounce in favor of same-sex marriage.
Remember, George W. Bush came out this summer and echoed Anthony Kennedy that people against gay marriage were evil.
