Tom Tancredo has been called a one-trick pony of a politician, a man out of step with his party, a bigot. The Republican congressman vehemently opposes illegal immigration, and he created an uproar last week when he talked about nuking Muslim holy sites."Unless I misread the political tea leaves, there is a great deal of support for what I say," Tancredo said.Experts say Tancredo has no chance at the White House, but like Ross Perot's campaign on a balanced budget in 1992, he has found an issue that could force other Republicans to treat immigration as a major issue.
