What is evident here is a failure to lead on this issue on the part of the President. It is clear that he is walking a very fine political line. With the economy being the focus of most Americans and politicians, the beginning of the general election (which will be a tight one), and various other circumstances, that is where all eyes are. The problem is that with the President’s open statement about "evolving" on the issue of marriage equality, he set himself atop a fence which he has been straddling for many months now. Whatever way he ends up taking, this seeming inability to make a public decision on this issue makes him look bad.
The unfortunate effect of this political calculation is that President Obama will look like he is doing just that: playing politics. That would be one thing if we were “merely” talking about fossil fuels versus renewable energy, or tax policy, or something of that nature. However, what we are talking about is basic human rights. No one likes their rights, or who they are, being played with like a football.
In terms of the presidential race, President Obama is still miles and miles more progressive than Mitt Romney on the issue of marriage equality. Romney is on record as supporting a federal amendment banning marriage equality (he has sign a pledge to that affect), he has given money to the support California’s Proposition 8. President Obama, conversely, is against a federal marriage amendment, he has spoken against various states’ efforts to amend their constitutions to ban marriage equality, and has (at the very least) left the door open to support marriage equality in the near future. President Obama's lack of a formal position, however, will call his leadership into question from all sides, and at a time when he can ill-afford this. When voters are looking at candidates, they want someone who will be a leader. This issue and how it has been handled by President Obama will not him to look like a leader...unless he changes course.
