Wiley has an amusing post about Obama's flip flop being considered as an asset by someone at LITW. Obama's shift was only common sense, since on the whole, NAFTA has been beneficial to this country, although maybe not as much in Ohio, where he made his original statement.
Overlooked, however, is the potential problem for Obama. During the primary campaign, he was able to get to the left of Hillary, because her perceived inevitability caused her to take a more moderate stance in anticipation of the general election in November. Because he was able to stake the ground, many in the Democratic Party went to him over Hillary, and he was able to hang on to secure the nomination. The problem for Obama is that the general electorate is not as left as the Democrats are. As a result, he now has to tack right for the general election.
But looming on the horizon, is the "suspended" campaign of Hillary Clinton. Remember, that Obama has only clinched the nomination based on the pledges of the superdelegates. Those superdelegates however, can switch their vote at any time. So, suppose Obama goes too far right, can Hillary go to the convention in Denver, and say that it is time to elect a real Democrat, not someone who's views are, shall we say, flexible?
You have to hand it to the Democrats, they can provide hours of entertainment when they are sure that they are going to win.
