Five-term Colorado GOP Congressman Scott Tipton was issued a stunning defeat in last night’s GOP primary.

Tipton, who was endorsed by President Trump, was defeated by small businesswoman and gun rights activist Lauren Boebert 55%-45%.

Boebert owns a restaurant called Shooters Grill where the staff can open-carry pistols in Garfield County.

Boebert accused Tipton of not being pro-Trump enough throughout her campaign and accused him of voting alongside Nancy Pelosi:

“In December, Scott Tipton voted alongside Nancy Pelosi to give millions of illegal immigrants amnesty and hand them a billion of our taxpayer dollars. In April, Scott Tipton joined AOC and her Squad to bailout Boulder. In June, I plan on term-limiting Scott Tipton,” Boebert said in an ad this month.

Trump endorsed Tipton by saying he is “a great supporter of the #MAGA Agenda! He fights for your #2A rights and the Border Wall.”

Boebert retorted that she didn’t believe the president had been briefed on Tipton’s voting record:

“I don’t believe President Trump has been briefed on Mr. Tipton’s voting record. Had he had known Mr. Tipton’s voting record, that endorsement would not have gone out,” she says.

Tipton may have been caught off guard in his crushing primary defeat. According to FEC reports, Tipton did not spend any money on television advertisements during his campaign.

Boebert’s unlikely victory over an incumbent Congressman wasn’t the first time she made political waves. In 2019, she confronted then-presidential candidate Beto O’Rourke over gun confiscation.
