bullsh!t. The Democrat party lurches left and loses every time. They win when they run as moderates. The right is is the opposite. The GOP wins when they run as conservatives and get trounced when they run as Dem-lite.
That helps to explain why someone to the left of Carter is now our president. As for Palin, maybe can win some more people over. I think the way to do it is cultivate the image of a serious candidate, someone who could mop the floor in any debate with GOP and dem candidates... and not by batting her eyelashes or (as her old mentor McCain often does) by conceding practically everything to the opposing side. You can argue all you want about everything she’s done up to now, but it isn’t enough to make her president.
