On CNBC's Behind the Money blog on Wednesday, Fast Money executive producer John Melloy promoted a left-leaning theory as to why the stock market has been on the rise lately: "While President Obama may not be Wall Street's ideal candidate, stock prices are rising on growing expectations he will be re-elected this November."

Melloy pointed to long-term political certainty as a reason for investor optimism and added: "The surge in President Obama's chances at a second term also have coincided with a string of better-than-expected domestic economic data this year, including an all-important drop in the unemployment rate."
