So last night the House Judicial Committee in RI heard from 197 people. 137 were supporters of marriage equality, 60 were against marriage equality.
If you want to know, supporters are 70% while those against are 30%.
I came up with similar when I worked the voter data out using percentage who actually vote, and polls from Brown, MERI and the Providence Journal. It came out that 29% want to put it to a vote on a ballot.
