Democrats are such spineless chickensh*ts. Meanwhile you have Collins acting as a full-on MAGAbot while representing a D-leaning state.
1) Collins is and always has been a center-Left senator
2) Maine isn't all that D-leaning any more
Collins is a Republican hack.
Collins is with Murkowski the only moderate/centrist Senator left in the Senate, they are the only two senators who are not voting +90% of the time with their party leadership partisan line
You're forgetting about Joe Manchin and Kyrsten Sinema.
