Tisha Casida is a 29-year-old southern Colorado-bred conservative. The Keystone XL Pipeline, she suggests, is safer and probably better for the environment than sending oil tankers across the Atlantic. The country's conflict over carbon dioxide, she hints, may be as much a waste of time as the war on drugs. She makes no bones that she is disappointed in her congressman, Scott Tipton, because he hasn't demonstrated leadership on a few crucial issues, like speaking out against the Patriot Act.
