Because he sure isn't getting any love from liberals.
This story mentions a bit about the attitudes of the Occupy Wall Street protesters:
"When Douglas Schoen, a Democratic pollster, sent an agent to Zuccotti Park, where the protests began, to make inquiries, he got back surprising data. Just 198 occupiers were polled, so this was hardly a scientific sampling, but an experienced pollster nevertheless is careful about whom he talks to. Just 48 percent said they will vote for Mr. Obama next year. Only about 15 percent are unemployed, and they clearly aren’t the downtrodden “99 percent” they claim they are. However, “We’re the 85 percent” wouldn’t make much of a message on a T-shirt."President Obama is in real trouble if these people are not solidly behind his re-election.
