I can see when liberals mistake when someone changes his or her mind of how heor she felt about something 5 or 13 years ago with flip flopping. They are after all ignorant, but when a conservative like you does, I am amazed.
Why should you be amazed? Willard didn't change his position on abortion gradually over 5 or 13 years - He changed it abruptly around the middle of 2005, i.e. less than 3 years ago. He appears to have did an abrupt about-face on the issue at right about the time he started thinking about running for President as a Republican, and realised that being radically pro-choice was going to be a no-go in the Republican primaries. Hence, he's a flip-flop - he adopted political positions based on convenience, not on principle.
When they do it with something to lose ill buy it, when they do it because they are running to a different constituency its a whole other ball game..
