Tuesday was a remarkable day in Rhode Island politics. First, the five-member GOP contingent in the 38-member state Senate -- including the chamber's low-key minority leader, Dennis Algiere -- offered its unified support for same-sex marriage. Then, and much more significantly, Senate Majority Leader Dominick Ruggerio found himself on the wrong side of a key vote in the Senate Judiciary Committee. Rhode Island is now on the cusp of legalizing same-sex marriage.
