Essentially, you pretend that Romney has the same tyrannical approach to governing as Obama.
With a Romney win, we have a great chance at retaining a congressional majority, and perhaps gaining one in the Senate too.
At least Romney would feel constrained by Constitutional norms, and not go off of the rails, in search of all of those policies you fear.
He’s no longer playing to the more liberal MA audience, rather the more conservative voters, across America.
