Illinois Republican Senator Mark Kirk is endorsing same-sex marriage.  Kirk joins Ohio Senator Rob Portman as the only Republicans in the Senate to come out in support of marriage equality.  In a statement, Kirk said, quote,  "Our time on this earth is limited  --  I know that better than most  --  life comes down to who you love and who loves you back (and) government has no place in the middle."  Kirk, who is back at work, is still recovering from a life-threatening stroke.
