Ken Buck joins call for new GOP gubernatorial nominee

Colorado Senate candidate Ken Buck (R) has added his voice to the chorus of Republicans calling for gubernatorial candidate Dan Maes to step aside.

"After having a lengthy conversation with Dan Maes, it is clear to me that Dan is struggling to determine the best path for his campaign, his family and for Colorado," Buck said in a statement. "I have decided that I can no longer support his candidacy for governor of Colorado."

Buck joins former Sen. Hank Brown (R-Colo.), former GOP Senate candidate Pete Coors and former state Senate President John Andrews (R), who have all called for Maes to step aside.
