A potential matchup in the race for governor is looking less favorable for Sen. Wendy Davis this week.

New numbers from Public Policy Polling show Davis trailing Republican frontrunner Greg Abbott by 15 points, with 15 percent undecided. The poll assumes Abbott wins his party’s nomination for governor and that no one runs as an independent.

The PPP poll also posited a hypothetical three-candidate matchup, assuming that Debra Media dropped her bid for comptroller and ran for governor as an Independent instead. In that scenario, Abbott still commanded a 10-point lead, with Davis holding onto 37 percent and Medina grabbing 9 percent.

The PPP poll surveyed 500 voters by an automated phone interview and has a margin of error of 4.4 percent.

Monday, a University of Texas / Texas Tribune poll showed Davis trailing by only six percent against Abbott in a head-to-head matchup, with that gap shrinking to five percentage points with Libertarian candidate Kathie Glass included in the race.
