Really? What's the thinking there?
2) The party in the White House loses seats in Congress. Giuliani will further entrench the Republicans as a minority in Congress and likely drive southern conservatives and pro-life Catholics back to the Democratic party. A Hillary Presidency will almost surely result in massive Republican gains in Congress and, possibly, set the stage for Republican control and another Republican revolution.
Simple. In one case we’re all together inside our fortified city, and the evil enemy we all recognize is outside the gates, ready to attack with her hordes. In the other case we’re all together inside our fortified city, and an evil enemy — supposedly one of our own that some mistakenly think is a friend — is within, organizing his supporters to come at us from behind as we focus on the enemy outside.
The real argument here is whether or not Giuliani is an enemy to our cause(s). I firmly believe that he is; I suspect that you feel differently. But if he is an enemy to our cause, it’s obvious that an enemy within is more dangerous than an enemy outside the gates — just as civil wars are much more more bloody and dangerous than even huge wars fought against outside forces.
