Are these klutzes going to continue to support Snowe and Collins?
I don't know if they have supported them.
The NRA supports those who have the best 2nd Amendment record. If there's a tie in their ratings, then they default to incumbents. It's one of the reasons that before the election in 2006, the rats only had 45 votes in the Senate. Other than the Kagan and Sotomayor votes, the rats have been loathe to touch the 2nd Amendment.
Snowe and Collins could be primaried, but that could mean that they're replaced by rats.
And Fancy Grahamnesty, or Lugar or any of the Dems who voted for her?
