Just 4 Senate Democrats Don't Support Marriage Equality

Sen. Tim Johnson, South Dakota
Johnson announced in late March that he's retiring from the Senate in 2014.  In theory, that might give a politician freedom to take a position at odds with South Dakota's conservative voters. But, on the same day, Johnson's office reiterated his opposition to marriage equality to the Huffington Post. "He has not changed his position on marriage equality," a spokesman said.
