Because the bigots in Maryland have turned in sufficient signatures to put a repeal of same sex marriage on the ballot:

Activists working to repeal Maryland’s same-sex marriage law have collected more than twice the signatures needed for a referendum — likely ensuring that the measure will be on the ballot for voters to decide in November.

The law’s opponents submitted 122,481 signatures in favor of a referendum; 55,736 are required. If enough are verified as legitimate, as expected, Maryland will be in the center of a national debate on same-sex marriage, with groups on both sides preparing to spend millions.

I’m still debating between writing in Stewart/Colbert or Colbert/Stewart, but I’m voting against the hate amendment.
