So Obama just wants to repeat the Republican mistakes with the Doc Fix adding more and more to the deficit in the middle of a fragile economy.

Obama has no solution!
Obviously, his solution is indeed to put this off until there are enough actual leaders in Congress willing to do their damn job, and sit down and figure out how to solve the matter for good... But since Republicans are only concerned with obstruction and political grandstanding in an election year, not actual leadership, a real solution is impossible.
Seniors on Medicare can't wait for Republicans to stop acting like jackasses, so the Dems are correctly doing what they can in the face of the constant jackass behavior... They have proposed a 'centrist' interim solution that has in fact been favored by Republicans for a decade, knowing that if it gets an up or down vote, several Republicans will side with Democrats and at least get this issue resolved for now... But instead of letting that happen, Republican leadership is hypocritically tying up the vote and trying to make political hay out of it.
Personally, I would rather the Dems call the Republican's bluff on it, propose an actual longterm solution, not an interim one, and let the Republicans filibuster on TV for days and weeks, and then explain to seniors in November why they wanted to play footsie with their healthcare.
Obama has no idea how to do anything. Where is Obama's solution? He doesn't even have a budget! He refuses to pay for his additional jobs bills which are billions and billions to the deficit.
An action with wide support of economists and even Fed Chairman Bernanke, who all fear that if the govt cuts spending right now, it could lead to a double dip recession.
Republicans proved that they don't know how to run the economy when they drove the nation off a cliff into this disaster, and they continue to prove that they don't know how to pull us out of it either with nonsense like this.
