Not a "rematch" per se but is there any chance Joe Heck could go for his old seat in 2018?
Perhaps. But it's never fun to come slinking back to your old seat after getting beat for your promotion. Very few ever do it (Steve Pearce in 2010 is the first to come to mind).
If we mention Heck, then I should also say it might be possible for Patrick Murphy in FL-18 as well, considering how popular he was in that seat.
Hell, maybe even bring Bruce Braley back to run in IA-01. That 2014 loss is looking less and less like Braley's fault, in hindsight.
Heck running for his seat again would probably would require Rosen trying to go for the big promotion - which I doubt will be the case. Brian Mast doesn't strike me as an Allan West type, so Murphy will have a tough time with Mast being the incumbent. And lol, Braley officially killed any chance he had in Iowa politics with the embarrassment of a campaign he ran in 2014.
