Gay marriage before Supreme Court? Cases weighed

The road to marriage equality is shifting from the ballot box to the Supreme Court. Three weeks after voters backed marriage equality in three states and defeated a ban in a fourth, the justices are meeting Friday to decide whether they should address marriage equality at the federal level.  The court also could duck the ultimate question for now and instead focus on a narrower but still important issue: whether Congress can prevent legally married gay Americans from receiving federal benefits otherwise available to married couples.
