$6,000: Cost of obtaining a Supreme Court seat for marriage cases.

Rob Reiner and Ken Mehlman speak to TPM in front of SCOTUS.

Jonathan Capehart urges caution on SCOTUS: "The quasi-triumphant coverage of this week's Supreme Court oral arguments in cases related to marriage equality is making me uncomfortable. Not because I don't want the high court to rule in a way that upholds the dignity and equal protection of same-sex couples who are or want to be married, but because I don't think lesbian, gay, bisexual and transgender (LGBT) Americans fully appreciate just how tenuous things are on the court right now. The undeniable forward momentum propelling today's hopeful enthusiasm could be the very thing that keeps the Supreme Court from going big."

Michelangelo Signorile: How we got to the Supreme Court. "What I want to say first is that the path to the Supreme Court by gay marriage advocates is a lesson for every movement. What took the LGBT rights movement to this moment, and indeed what has taken us to moments of truth and potential victory more often than not, are those who went against the established leaders and groups and ultimately pushed an agenda from the grassroots."

CNN: "Rob Portman effect" fuels support for same-sex marriage. "The number of Americans who support same-sex marriage has risen by almost the same amount in that time – from 40% in 2007 to 53% today – strongly suggesting that the rise in support for gay marriage is due in part to the rising number of Americans who have become aware that someone close to them is gay."

Politico: GOP youth 'evolve' on gay marriage.

Alabama Republican Senator Jeff Sessions: "I think people are free to marry any way they want to," Sessions said. "But churches are free to set standards for marriage."

Republicans see cash opportunity in marriage equality support: "Republican fundraiser Jim McCray agreed. 'I think it will open up donors across the board, because it demonstrates Republicans are trying to recreate the big tent they were known for,' McCray said. It's not clear how much money could come from donors supportive of the party's move toward new thoughts on gay marriage. Pro gay-rights donors have long been an important source of campaign cash for Democrats, including after President Barack Obama pushed through a repeal of the “don't ask, don't tell” policy, which barred openly gay people from serving in the military. And operatives believe the money is there for Republicans, too."
