Senate candidate Tammy Baldwin supports President Obama's position that marriage should be left up the states.
"The role of defining marriage has fallen to the states, and it has always been with the states," she said during an interview on MSNBC's Daily Rundown.
"Should it be?" interrupted Chuck Todd. "I know it always has been. Should it be, should we have 50 different laws on marriage?"
"We have since the founding of this country," Baldwin said, "and I don't see anything changing."
Some activists have expressed disappointment that while Obama came out for marriage equality in an interview with ABC this week, he said the laws should still be decided on a state-by-state basis. North Carolina is the most recent state where voters have approved an amendment to their constitution banning same-sex marriage and other non-marriage unions. Meanwhile, six states plus the District of Columbia already allow same-sex marriage and Washington and Maryland are poised to do the same next year.
