WASHINGTON (AP) - Mitt Romney may lead in delegates and Rick Santorum might have momentum, but neither of the two leading Republican presidential candidates is having an easy time exciting even his own voters.
Out of a dozen states where voters in the GOP contest have been polled, most Romney voters say they strongly favor him in just five of them. A majority of Santorum voters felt that committed to him only four times out of 11 states where he was on the ballot and voters were surveyed.
Each man is struggling to consistently spark the intensity that could separate him from the pack.
On average, about half Romney and Santorum voters say they strongly favor their candidate. That comes from entrance and exit polls of voters in 12 states.
