You don't think trends will continue in CO-03?
CO-03 has terrible undercurrents for Democrats - a largely ancestral Democratic base in the Southern parts of the district, and a large set of low-propensity conservatives in other areas. The ski-resort types are high-turnout voters who won't be able to increase their vote share in a presidential year. But it's a complex district, and Boebert is a uniquely terrible candidate so this will probably be closer than Republicans would like, but I still think it favors them in the long-run.
the people moving in and out of CO-03.. it does favor Democrats.
If a non-Boebert is a the GOP nominee.. do think the GOP holds it for sure though.
