Sen. Debbie Stabenow (D-Mich.) holds a fairly comfortable 10-point lead over her likely opponent, former Rep. Pete Hoekstra (R-Mich.), according to a poll conducted for the Democratic Party of Michigan by Greenberg Quinlan Rosner.

Stabenow led in the poll with 52 percent support to 42 percent for Hoekstra.

She has been favored in most polls, but Republicans are hoping to make the race close. Generally, if an incumbent is polling above 50 percent in their reelection matchups, they're on relatively safe ground.

The poll of 603 likely voters was conducted from Dec. 15-19 and has a margin of error of plus or minus 4 points.
