I expect him to flip flop. All politicians do, and now he's got the nomination wrapped up in his party he needs to move closer to center to appeal to the masses.
This is really about liberal re s like boutons and Dan calling McCain a flopper when their own 'chosen one' is right there with McCain on changing his position. It gets old seeing boutons bring the McFlipFlop when Obama is just as guilty.
In short, it's a non-issue but if the resident libs on the board are going to about every perceived McCain flip flop, they're going to get every Obama flip thrown back in their face.
