NORTHGLENN, Colo. (CBS4) – The congressional candidates in Jefferson County had a close encounter, and it wasn’t a planned event.

Saturday morning Republican Joe Coors organized his campaign to begin going door-to-door. At the same time incumbent Democrat Ed Perlmutter was doing the same thing just a few blocks away.

Colorado’s District 7 is one of the most watched congressional races in the country and one of the closest. The candidates say every vote counts.

“Stay away from arguing, because if you get in an argument you’ve lost your time because the next house down the road could be a yes vote and you’ll miss them,” Coors said.

“We’ve got to just do all the things we know how to do,” Perlmutter said. “Walking door-to-door, making the phone calls, visiting with people at the grocery stores, and really making that kind of voter contact that I think makes the difference.”

Political analysts say the race takes place in what could be the most important county in the election.

Perlmutter is seeking re-election for his fourth term.
