Dismiss us prolifers at your own peril - and I was one of those who did vote for the pro-choicer in 98 because of Stabenow. Others, such as my mom are not so forgiving, and I'm a lot less forgiving on that issue now than I used to be.
Dan your vote really isn't in play in a general election, since the Dem will almost always be more pro abortion than the Pubbie, certainly in a presidential race, and given the other issues in play, your ballot is a given. It is cross conflicted voters that matter on this issue, not you.
