A new USA Today/Gallup Swing States Poll finds President Obama just ahead of Mitt Romney in the dozen key battleground states, 47% to 45%.
That's much closer than the lead of 9 points for Obama in in late March.
"But the poll also finds a reversal in what has been a key GOP asset in the five previous battleground surveys taken since last fall: an edge in enthusiasm among voters. For the first time, Democrats are more likely than Republicans to say they are extremely or very enthusiastic about voting -- a shift from a 14-percentage-point GOP advantage at the end of last year to an 11-point deficit now."
