The tea ☕
- In September a PAC called American Muckrakers filed a House ethics complaint against Boebert with claims about her conduct with staffers. Boebert called it utterly false, the named staffers denied it, and a judge gave her a temporary protection order against the man who filed it.
- President Trump said in June he would love to see a primary challenger against Boebert after she campaigned for Rep. Thomas Massie. It was too late to file, so she went to the general election with no primary opponent.
- Laubacher switched from Republican to unaffiliated to Democrat before running. At a debate she faced pointed questions about the party switches and her move within the district, which she said was only 10 miles.
