President Barack Obama has lots of reasons he wants to hold on to the White House in 2012.

There’s energy policy, for example, which he would like to revamp. There’s immigration reform, which he hopes to “implement.”

But at a fundraiser on Monday night, the president said the real challenge he had left to handle was “fixing” the political atmosphere in Washington.

“The challenge we have now is fixing our politics,” Obama said at fundraiser held at a private home in Washington.

“That is probably the biggest piece of business that remains unfinished. That’s probably the area where we’ve been most stymied over the last three years.”
