The new Rasmussen Reports poll has Democrat Richard Blumenthal slipping below 50 percent, but still leading Republican Linda McMahon, 47 percent to 40 percent.
The first post-primary poll shows no bounce for McMahon after her victory over Rob Simmons and Peter Schiff. Her support is unchanged from the previous Rasmussen survey on July 15.
The poll of 500 likely voters was conducted Aug. 11, the day after the primary. It was released today.
