Obama promised entitlement reform. He had a debt commission - which he frankly ignored. Half of his campaign is predicated around attacking entitlement reform. Every powerful interest group in the Democratic Party is lined up against entitlement reform. The base has rallied against it.
Which is mostly silly election year politicking. The fact is, Obama released a $3.6 trillion deficit reduction plan last September, and he agreed to a $4 trillion plan including entitlement reform last summer. This is all public knowledge. $4 trillion long term deficit reduction is in his 2013 budget.
At the end of the day, I'm skeptical of all of these plans. In 1995, the goal of balancing the budget by 2002 was considered a reach. And indeed, the 2002 budget failed to be balanced-- but the 1998-2000 budgets were. In 2001, it was thought that the debt would be paid off by 2010. And so on. These things aren't as predictable as fiscal planners think.
But to say Obama hasn't put something on the table is false. Yes, Democrats want to protect the social safety net relative to Republicans, so they're willing to go slightly higher taxes for the rich and would vote slightly smaller entitlement cuts. Yes, they're making a lot out of these differences in the campaign. But despite all the partisan bickering the actual differences in what the parties are willing to vote for at the end of the day, in terms of numbers, are not all that great.
It seems as if you're trying to convince yourself of this just be repeating it.
