The latest Rasmussen Reports national telephone and online survey of Likely U.S. Voters finds that 46% would choose the Republican candidate if the elections for Congress were held today. Forty-five percent (45%) would vote for the Democrat. Three percent (3%) prefer some other candidate, and six percent (6%) remain undecided.

A week ago, Democrats held a 47% to 44% lead.

This is the first poll showing a GOP lead, and it may matter: while often accused of bias, Rasmussen was the only major pollster in 2016 to predict a Trump victory; Rasmussen was also the only major pollster whose prediction was proven correct.
