Rasmussen released a poll Monday showing Democrat Chris Murphy up by six percentage points in his U.S. Senate race with Republican Linda McMahon, 51 percent to 45 percent.
The poll is based on a one-day telephone survey Sunday, the same day that Bill Clinton headlined a rally in Waterbury for Murphy. It has a margin of error of plus or minus 4.5 percentage points.
The poll was released five days after a Quinnipiac University poll also found Murphy with a six point lead, 49 percent to 43 percent.
At the time, the McMahon campaign called Quinnipiac’s poll an outlier, pointing to earlier Rasmussen Mason-Dixon polls that show the race a dead heat.
