Obama is a scarily good orator. I just don't see anyone in the Republican primaries who can possibly hope to match him in, say, a presidential debate. They all have faults. The likes of Perry and Bachmann obviously have more than most, but Romney, for example, is way too stiff to take on Obama.
Gingrich, while rather more well spoken, is simply too much of an unsuffrable twat, it veritably shines through. Paul is quite well spoken, and has an honest, serious manner about him. Unfortunately for him, he's also quite insane, which is hard to hide in a Presidential debate.
I can't wait.
