No way. We need Vermont. If anything, we need more left-wing states. I'd rather Canada give up BC or its Atlantic provinces. Admitting Atlantic Canada as four separate states would be quite good for future Democratic prospects. It wouldn't look too bad on a map either.
Trying to imagine PEI (Pop. 140 000) as a state
Each of the Atlantic provinces is smaller than MT, and NL has a smaller population than WY. Taken together the Atlantic provinces would fall somewhere between NM and NV in population. It's hard to imagine the US taking them as four states even if there was such a petition.
