“There are some pretty big changes happening out there with the voters,” Penn said during a conference call.

Penn pointed to a new Reuters/Zogby poll released Wednesday that called Obama’s 47-44 edge “statistically insignificant” after showing Obama up 14 in February.
The poll also showed that Obama’s seven-point February lead over McCain in a potential primary has reversed to an eight-point deficit. Clinton, meanwhile, has narrowed McCain’s lead from 12 points to eight.
Penn said Clinton’s “ability to beat McCain” has drawn voters to the campaign even though the poll shows the candidates tied in trailing McCain.
A Gallup daily tracking poll also shows a swing for Clinton. Clinton is up seven points in Wednesday’s Gallup poll. Obama led the tracking poll by eight points on March 1.
