Which Republican candidates could become difficult to dislodge if elected?

[hyouzel the predictor]

Definitely Kean (outran Biden by like 10 points in the old district which now is narrowly Dem won) and potentially some rural tossup districts (IA-03, MI-07/08, etc) that tend to stick with their incumbents... I actually think Kean outlasts Fitzpatrick who goes down in 2026 at the earliest whereas Kean has a lot more breathing room just BC of the makeup of his district
