The first time????? Kerry does it all the time. Take gay marriage. He came out hard against the defense of marriage act, calling it hateful and just like banning interracial marriage. Now Kerry is all in favor of a state banning gay marriage, which he considered a bigotted position a few years ago. Look at trade. Kerry favored NAFTA and other free trade agreements, now attacks Bush for all the outsourcing. Look at defense. Kerry proposed some of the biggest cuts in military spending in history, but now criticizes Bush for a weak military. Look at the deficit. Kerry voted against a balance budget agreement numerous times, and now bitches about the deficit. What issue hasn't Kerry been firmly on both sides of the fense????
I think in that phrase he was referring to Israel's security fence.
