Former Republican U.S. Sen. Olympia Snowe is putting her support behind a bill to open Maine's primaries.
The Democrat-sponsored bill would make it possible for unenrolled voters to cast a ballot in party primaries.
Snowe said in a press release from the group Open Primaries Maine: “In order to help ensure that candidates better reflect the ideological pragmatism of most Americans, Maine should enact semi-open primaries.”
Participating voters would not automatically become enrolled in a party after voting.
Maine is one of only 14 states that maintain closed primaries.
