Sen. Michael Bennet of Colorado, a Democrat who had been seen as increasingly vulnerable to a Republican challenge, has strengthened his numbers against the two leading GOP contenders, according to a
Public Policy Polling survey conducted May 14-16.
That result comes a day after PPP
released a poll showing that Bennet had widened his lead over his rival for the Democratic nomination, former state House Speaker
Andrew Romanoff.
Bennet leads former GOP Lt. Gov.
Jane Norton by 44 percent to 41 percent, with 14 percent undecided. In a PPP poll conducted March 5-8, the two were tied at 43 percent each. The margin of error is 3 points.
Bennet leads Weld Country District Attorney
Ken Buck by 45 percent to 39 percent, with 16 percent undecided. Bennet led Buck by 46 percent to 40 percent in early March.

Norton had been a heavy favorite to win the GOP nomination but the
PPP poll on Tuesday showed Buck gaining on her.
Romanoff leads Norton by 43 percent to 41 percent, with 16 percent undecided, and Buck by 41 percent to 38 percent, with 21 percent undecided.
"The political climate is starting to look better for Democrats and Michael Bennet's improved standing is a clear example of that," said PPP's Dean Debnam. "Jane Norton, at least so far, is not looking like a particularly strong opponent."
