The vast majority of Americans — roughly 75% — do not support Sen. Bernie Sanders’ proposal to enfranchise all prisoners, but many are open to giving voting rights to non-violent inmates, according to a new INSIDER poll.

Only 15% of respondents said all prisoners — regardless of their crimes — should keep their voting rights while behind bars. Meanwhile, 20% said only voters convicted of non-violent offenses should be allowed to vote.

During a CNN town hall last Monday, the Vermont senator was asked to clarify if he supports voting rights for people like the Boston Marathon bomber or people convicted of rape. Sanders replied that even “terrible people” should be allowed to vote, contending that disenfranchising any group of people is a “slippery slope.”
