For the GOP to be whining about John Edwards lacking experience in international relations is beyond absurd. When George W. Bush got handed the presidency, he'd never even been to Europe as a tourist. Hell, he'd never even held a job for more than a few years each.
The GOP's level of venom aimed toward Edwards is a reflection of their level of fear. Apparently they worry that Edwards shines too much when compared with Go Fuck Yourself Dick Cheney.
If the Democrats were wise, they'd ask the American public who'd make a better president, a healthy young man with an appealing personality, or a crusty old fart with a machine regulating his heartbeat.
Seems like an easy choice to me.
