re: Define "everyone"
"Is it an official, or even unofficial, Republican position that someone who commits a felony and who serves his or her time ought to be confined to a permanently disenfranchised underclass, beyond redemption and beneath contempt, forever after?"
Is it official that dems will ignore any law they don't like? Some states have these restrictions, other states don't. If the people of Maine want felons in jail to vote, then that is a decision of the people in Maine.
I think that the Dems position is that any decison made by people of Masschusetts should apply to all other states.
