Democrat Karl Hanlon launched a TV ad campaign Wednesday in the primary race to challenge U.S. Rep. Scott Tipton, a four-term incumbent, in Colorado’s 3rd Congressional District.

Hanlon, a Carbondale rancher and water attorney, takes aim at Tipton and President Donald Trump in a trio of ads set to air on broadcast and cable in the Pueblo, Grand Junction and Denver markets.

“Our communities mean too much to me to sit back when people need help,” Hanlon says in one ad. “We’ve got the highest healthcare costs in the country, thanks to Tipton and Trump. It’s time to protect our Colorado way of life, and fight for change.”

Hanlon faces former state Rep. Diane Mitsch Bush, D-Steamboat Springs, and former Eagle County Commissioner Arn Menconi, the 2016 Green Party nominee for the U.S. Senate, in the June 26 primary. Mail ballots go out to voters next week.

A spokesman for Hanlon’s campaign wouldn’t say how much the candidate is spending on the ads but called the buy “substantial” and said it will blanket the district.

He’s the first candidate to hit the airwaves in the race.

The 3rd CD, one of the largest in the country, covers most of the Western Slope, Pueblo County and the San Luis Valley. Tipton has held the Republican-leaning seat since he unseated a Democratic incumbent in 2010.

While he won by 14 points in the last election, state and national Democrats are targeting Tipton this year. A poll commissioned earlier this month by progressive groups showed Tipton in a statistical tie with a Democratic opponent.
