Serving the 4th District for nearly 10 years was the highest honor of Ken Buck’s life, the soon-to-be former Republican Congressman said before kicking the party he was also elected to serve squarely in the nuts on his way out the door.

Buck’s decision to end his congressional career after this term came as a surprise to few Republicans, who’ve been getting mighty miffed over his newfound role as a political commentator on MSNBC and CNN where he’s been more than happy to trash his own party.

His final goodbye seems to cement his creds as a future “Republican” commentator on those same networks, where we expect him to continue criticizing the party’s unsteady equilibrium that he helped to create as a member of the Freedom Caucus.

Adding insult to injury, Buck gave his departure scoop to MSNBC’s Andrea Mitchell, which drew criticism from former state GOP chairman and fellow Republican Party grumbler Dick Wadhams.

“I think it is offensive that Ken Buck would announce that he’s not running for reelection during an interview on a national cable TV show rather than returning to his district and thanking the people of the 4th CD for the honor and privilege of serving in the U.S. House of Representatives,” Wadhams told Colorado Politics.

So anyway, out with the old, in with the new!

The Denver establishment media is burning up the phones calling every Republican who may or may not live in the district to see who will step up to the plate to run for the seat.

Already in the race for the GOP nomination are Weld County Council member Trent Leisy and first-time candidate Justin Schrieber. Colorado Polities reports Democrats Isaac McCorkle, John Padora and Karen Breslin are also running in that party’s primary.

Here’s the scorecard as of, right now.

Marshall Zelinger over at 9News wins Most Aggressive Caller award for burning up the phones to learn which Republicans’ lives he will soon be trashing.

This is what they’re telling him:

Not running, please go away

Former state GOP Chair Kristi Burton Brown

State Senator Barb Kirkmeyer

Former state lawmaker Greg Brophy

Douglas County Commissioner George Teal

Maybe

Former District Attorney George Brauchler

State Rep. Richard Holtorf

Former U.S. Senate candidate Deborah Flora

Logan County Commissioner Jerry Sonnenberg

Douglas County Commissioner Lora Thomas

Douglas County Commissioner Abe Laydon

Not taking Zelinger’s calls but being talked about

Former University of Colorado Regent Heidi Ganahl

House Minority Leader Mike Lynch

The district leans heavy Republican with 35% compared to 17% Democrats, so stay tuned!
