The Washington Post's Plum Line blog:

"...The First Lady [said at a fundraiser last night] that Obama’s appointees to the Supreme Court will uphold the right to “love whomever we choose.”

Though her aides say she has said this before, gay rights advocates are seizing on the language for the first time. One prominent advocate, Richard Socarides, says the language will be received as code for saying that Obama’s Supreme Court appointees will uphold the right to gay marriage. Several cases involving gay marriage may be headed for the highest court, so to advocates, Ms. Obama’s language seems telling.

But the First Lady has repeatedly denied backing marriage equality. And a campaign official insists to me the new language isn’t significant."
