It looks like freshman Congressman John Salazar already has an opponent for 2006. State Representative Joshua Penry, who bills himself as a "Citizen Legislator" while representing Delta and Mesa Counties, is preparing to challenge Ken's older brother.
Penry is considered to be personable and very bright, and will be extremely well-funded. Penry doesn't carry the baggage that Salazar's 2004 opponent lugged around, either.
If John Salazar is re-elected it certainly reflects well for the Salazar Machine, but his race will put pressure on Ken. If John loses in 2006, the vultures will start circling around Ken well before 2010.
UPDATE: Here's Josh Penry's state house campaign website. You've gotta love this incredibly goofy glamour shot picture of Penry and former Congressman Scott McInnis at the bottom of the website; they look like they're getting ready to shoot a late-night ad for ambulance chasing attorneys.
