----And that leaves out the battle between Giuliani cultural liberals and cultural conservatives that will cripple the 2008 GOP nomination fight.----
Very true -- that's a big problem looming on the horizon. What could mitigate it, ironically, is Hillary herself. She's as hated among Republicans as Bush is among Democrats, and that could get Republicans to put aside their differences and unite around a single candidate early, as Democrats did around Kerry this year. They made a poor choice, of course, and that's the key: the Republican candidate must be an exciting, inspiring figure who will motivate the swing voters to turn out for him or her, because they will not turn out against Hillary.
And even all of this does not take into account Hillary's likely attempt to set up a third-party candidate to siphon Republican votes. Hell, it's how her husband won. Which brings us back to immigration: Unless the GOP acts on this, it is looking at a very possible Perot-style split over the issue that would hand the election to the Hildebeast.
2008 will be a nail-biter.
