Write-in: The entire human race via meteor strike.
Yeah, and Sue Kelly and Charlie Bass were beloved centrists who were never going to lose... the history and record are what they are, but these guys have never been seriously challenged by viable candidates before in a dramatically changing environment. Maybe they'll cruise to reelection this year, but until they do, it's hubristic to presume that nothing has changed.
I think it's hubristic to think that anything has changed. There is a big difference between moving moderate-to-liberal independent voters and hard-wired Cuban voters.
Winning GOP-held seats in New England is very different than winning GOP-held seats in Florida. The Kelly/Bass seats have been trending Democratic for at least a decade. Democrats breaking into the Cuban vote is something that's still in the planning stage.
