In Connecticut, Siena has Obama by 15, Murphy by 2

Another poll shows Connecticut tilting strongly toward President Obama, with the contest for the open U.S. Senate seat still close.


A survey by the Siena Research Institute taken long before last night’s presidential debate found Obama with a 15 percentage point lead over Mitt Romney. He led, 53 percent to 38 percent.


In the Senate race, Democrat Chris Murphy led Republican Linda McMahon, 46 percent to 44 percent. As other polls have found, the heavy negative advertising has left Connecticut voters with an unfavorable view of each.


The Siena survey of 552 voters was released today, but it was taken from Oct. 4 to 14, an unusually long time to be in the field. The Senate candidates had two televised debates during that time, with a third held the day after the survey was completed.


It has a margin of error of plus or minus 4.2 percentage points.
