Attorney General Eric Holder’s call to restore voting rights to felons after they’ve served their time in prison has split Senate Democrats.

Liberal Democrats who are not facing tough re-elections this year say it’s the right thing to do, but vulnerable incumbents are steering clear of the proposal.

Holder has become increasingly outspoken recently. This week he declared that state attorneys general are not obligated to defend laws that are discriminatory.

Political experts say barring ex-felons from voting impacts African Americans disproportionately.

Sen. Mark Warner (D-Va.), who faces a competitive challenge from former Republican National Committee Chairman Ed Gillespie, is torn over the idea.

Warner supports restoring voting rights to non-violent ex-felons but he’s not sure it’s a good idea to automatically enfranchise former violent felons.
