Do you have any idea what the GOP is thinking by going all-out on this war against contraception? I can't imagine what possible political benefit it could have. They might as well campaign in favor of segregated water fountains.Oddly enough, this is exactly what I was writing on over at Plum Line today, although it just got published now. So I'll send you over there for the answer. Short version: parties sometimes go ideological, suffer the consequences.
To expand a bit, I'll go back to one of the things that I've talked about less lately but I think is still functioning: that there are a lot of people making money off of being conservative who have perverse incentives. One of the reasons that parties work, and therefore that democracy works, is that normally both parties have strong incentives to try to win elections. But Rush Limbaugh probably makes more money if Republicans lose (although he doesn't get to hang out at the White House). More conservatives are going to buy books about Barack Obama in 2009 than they did about George W. Bush in 2001. So that is something to worry about within the system, along with the other reasons that parties sometimes leave the mainstream.
