According to CNBC’s Bob Pisani if you have money in this market right now, the biggest risk to the downside probably comes from... politics.

Specifically, Pisani worries about the squabbling that resulted last week over whether to re-appoint Ben Bernanke as Fed chief.

Bernanke may be reconfirmed, says Pisani, but significant damage has already been done to the perception of the Fed's independence.
