Also, Ron Paul did vote to authorize military force in Afghanistan after 9/11 and he never called for a declaration of war then.
Uh, I'm not so sure. I did a search for 2001 house bills under the key word 'Military' and the closest I came up with is the below link...

This page gives the vote totals. If you scroll down to the map and click on Texas, you'll see that Ron Paul voted against this bill. None of the other bills seemed to meet the criteria of 'military force'. Even this one is not the best hit.
If you have information on some other, more pertinent bill, I'd appreciate it's link.
