But since then, Perlmutter’s fellow Democratic Congressman, Rep. Jared Polis of Boulder, joined the race. Polis, who is independently wealthy, is expected to spend large amounts of his own money on his campaign, and there are at least two other high-profile Democrats vying for the Democratic nomination: ex-state Treasurer Cary Kennedy and former state Sen. Mike Johnston.
Kerr sent a statement following the news that Perlmutter was dropping out of both races:
"Ed Perlmutter has been a friend, a mentor, and a hardworking public servant for the people of Adams and Jefferson Counties. I wish him nothing but the best in whatever path he chooses next," he said in the statement.
But the Republican crowd is also already getting crowded, with George Brauchler, Vic Mitchell and Doug Robinson among the GOP field who have declared thus far.
Robinson noted Monday that Perlmutter's exit pushes the Democratic field further to the left, as Polis is now the most well-known name in the field.
"This is a huge shift to the left in the Dem field," Robinson tweeted. "A far left candidate won't sit well with CO voters."
