Note he says it was a brush with death that caused him to change his mind, not a brush with God:
REUTERS – Senator Mark Kirk announced on Tuesday that he supports gay marriage, suggesting a brush with death had helped shift his attitude as he became the second Republican to join dozens of Democratic senators who back homosexuals’ right to wed.
“When I climbed the Capitol steps in January, I promised myself that I would return to the Senate with an open mind and greater respect for others,” said Kirk, an Illinois senator who returned to the Senate in January almost a year after suffering a major stroke.
“Same-sex couples should have the right to civil marriage,” he said in a statement. “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 – government has no place in the middle.”
