How hard it is to get Obama to say he supports ending discrimination on gay marriage, facing a country with a 33-1 record of states voting for discrimination, is a little taste of how earlier leaders in the civil rights movement faced difficulty in supporting the end of Jim Crow laws that had wide popular support in many places.
President Kennedy talked about how the public could only handle change at a certain speed, that seems a bit similar to Obama spending years 'evolving' on this.
Of course, evolving meant 'trying to have it both ways', holding out a carrot for the non-bigots while minimizing the cost with the bigots.
But that's the issue the leaders face on both issues - it can put their election, their legislative program, at risk fighting this battle and they have to make choices.
I was watching a biography of Clinton that reminded how in the middle of his budget battle he mentioned he was for ending gay discrimination in the military, and it took over the political discussion threatening his budget, resulting in the compromise no one was happy with - because Colin Powell and Sen. Sam Nunn and others fought for discrimination of 'Don't Ask, Don't Tell'.
I dont give Obama as much credit for leadership on this as I give to earlier leaders who supported civil rights, but it is some leadership and clearly better than the right.
Wall Street has unsurprisingly switched from Obama in 2008 to Romney in 2012, and it's reported he's partly made up for it from donations from people favoring gay equality.
This issue was going to dog him all through the year making him look weak for not taking a clear position, so it seems to me this was a calculated political move.
Which puts him far ahead of Romney on the issue.
So we have a choice: the candidate serving casino gambling corruption of Wall Street taking American's wealth and threatening the economy, or the one for basic rights.
Was Biden's interview a planned part of the process? Some say no, I have to suspect it. Not that there's anything wrong with that, pun intended.
