A Republican poll has given Minnesota GOP Rep. Jason Lewis, who’s consistently ranked among the year’s most vulnerable incumbents, a narrow lead in his rematch against Angie Craig in the 2nd District. 

Lewis led the Democratic-Farmer-Labor nominee 46 percent to 43 percent — within the margin of error — in the survey conducted by WPAi for the National Republican Congressional Committee and the Lewis campaign, and obtained first by Roll Call. Eleven percent were undecided. 

In its polling memo, WPAi noted that Craig’s share of the vote has slipped. An earlier WPAi poll, conducted Aug. 18-21, had Lewis ahead 46 percent to 45 percent, with 9 percent undecided. 

WPAi surveyed 412 likely voters from Sept. 29 to Oct. 1, with 38 percent of interviews conducted via cell phone. The poll had a margin of error of plus or minus 4.9 percentage points.  

The 2nd District, which narrowly backed President Donald Trump in 2016, is regarded as a top Democratic pickup opportunity this year, especially since a third-party candidate who earned nearly 8 percent of the vote two years ago isn’t on the ballot this time. Lewis defeated Craig by less than 2 points in 2016.

Polling from both sides has showed a close race. Inside Elections with Nathan L. Gonzales rates the contest Tilts Democratic.
