BOSTON (CBS) — Massachusetts allowed mail-in-voting for the first time in the Sept. 1 primary, and new numbers show a lot of voters took advantage. A plurality of voters chose to cast their ballot by mail as opposed to showing up to the polls in person on Election Day.

Data from Massachusetts Secretary of State William Galvin shows 812,973 people returned ballots by mail. That amounts to 47.6% of total ballots cast.
