Sen. Tim Johnson (D-S.D.) on Monday became the latest Democratic senator to embrace gay marriage.

"After lengthy consideration, my views have evolved sufficiently to support marriage equality legislation," Johnson said in a statement released through his office. "This position doesn't require any religious denomination to alter any of its tenets; it simply forbids government from discrimination regarding who can marry whom."
