You really ought to wait for re-districting. It's possible that only NH will have any GOP opportunities and it's doubtful Bass can defeat Kuster again.
You're saying that there might be gerrymandering in Connecticut?
They have some legal limits to what they can do, but within those limits they're fairly well gerrymandered right now. They only need to undo that to drastically reduce the GOP's chances in the 5th.
Considerable parts of Bass' district is headed Vermont way. It's exceedingly unlikely that it can ever be a safe GOP seat again, though if 2012 turns out favorable and/or he gets a weak opponent, he certainly could hang on. Thus the most plausible answers are 0 and 1. I went with 1.
