There's just one week to go until the election. And President Obama has endorsed the freedom to marry in all four of the states that will vote on the issue. Meanwhile, Mitt Romney has endorsed a constitutional amendment to ban marriage equality.

In just days, four states will vote on the freedom to marry. Polling is still very close. Visit AFER.org/election2012 for ways that you can help all of those campaigns. Meanwhile, President Obama has lent his support to all four races.

In Washington, Obama spokesman Paul Bell said "the President supports a yes vote to approve Referendum 74."

In Maine, his press secretary says "The president believes same-sex couples should be treated equally and supports Question 1."

In Maryland, Obama said, "you have a chance to reaffirm that principle [of fairness and equality] in the voting booth in November. It's the right thing to do."

And in Minnesota, which will vote on a marriage ban, Obama officials released a statement reading, "the Minnesota ballot initiative ... would single out and discriminate against committed gay and lesbian couples -- and that's why the President does not support it."

Meanwhile, an advisor to Mitt Romney confirmed this week that the candidate supports a federal constitutional amendment to prohibit the freedom to marry.

Polling in those crucial state races is still close. In Washington, an Elway Poll shows support for Ref 74 dropping under 50 percent. It's now leading, but just barely, at 49 to 45 percent.

In Minnesota, the proposed marriage ban has 44 percent support to 51 opposed.

And there's one more state with a vote next week involving the freedom to marry. In Iowa, voters will decide whether to retain one of the Supreme Court justices who struck down the state's marriage ban.

It was a unanimous decision by a conservative court. But anti-gay activists are pushing to unseat all of the justices. Now Justice David Wiggins is being targeted by groups like NOM.

He needs 50% support to keep his seat, and just as in the other states, it's going to be close. A Des Moins Register poll shows he has 49% support, with 41% voting to unseat.

There's still time get involved in Iowa, as well as in Maine, Minnesota, Maryland, and Washington. Visit AFER.org/election2012 for resources that you can use to spread the word about these races and contribute to the campaigns.
