It's going to be a busy primary in Colorado's Fifth Congressional District.
Two more Republicans say they will campaign to replace Congressman Joel Hefley.
They are state Senator Doug Lamborn and a former administrative director for Hefley, Jeff Crank.
The six-county district is heavily Republican.
Former El Paso County Sheriff John Anderson is already seeking the G-O-P nomination.
The only Democrat in the race so far is Jay Fawcett, a former Air Force Academy professor and Gulf War veteran.
Hefley said last week he won't seek and 11th term.
