They're out there. I'm watching Rep. Ron Paul (R - TX 14th CD) on C-SPAN right now. Admittedly - and I'm sure due to the GOP keeping guys like him under wraps - I knew very little about this guy other than he took an anti-war stance on Iraq. He's running uncontested this year in his district, and isn't so sure about suporting Bush. His politics are downright...well, we used to call folks like him "moderate" before we tilted so far to the right.
Check him out.
