It's just one poll. Could be an outlier. But still:

Sen. Bernie Sanders (I-VT) lags behind former Secretary of State Hillary Clinton by just two points, nearly wiping out Clinton's previous 31-point lead, according to a nationwide Quinnipiac poll released Friday. The poll showed support for Clinton at 44 percent, with Sanders close behind at 42 percent. This represents an enormous change since the previous national Quinnipiac poll in December, which showed Clinton beating Sanders 61 percent to 30 percent.

Is it too late for Russ Feingold to get in the race?
