The fifth district in Colorado Springs has been held by the GOP since its creation in 1972 -- but in another sign of mounting GOP travails, a new poll released today shows that Republicans are in serious danger of losing the seat being vacated by retiring GOP Rep. Joel Hefley. The Denver Post reports today that a new Mason-Dixon poll -- the first public poll on the race, it appears -- shows that Dem Jay Fawcett is tied with GOPer Doug Lamborn for the seat, at 37% apiece. The Post notes that the district is two-to-one Republican. Says Bob Loevy, political-science professor at Colorado College: "It appears that Lamborn is now the first Republican who has ever had to fight hard to take that seat."
