Forty-five percent of people said they would like to continue to see Democratic Senate control, while 42 percent would prefer a switch to the GOP. 

However, 41 percent of independents would like to see GOP control of the Senate, while 38 percent would like to see Democrats maintain control. 

The majority of registered voters, 53 percent, said President Obama would not factor into their midterm decision. Twenty-five percent said they would vote to send a message that they oppose Obama. Another 20 percent said they would vote to send a message that they support Obama. 

The president's approval rating is largely unchanged at 43 percent, while 55 percent disapprove of his job as president. 

The poll surveyed 1,008 adults, including 911 registered voters, and contains a margin of error of plus or minus 3.5 percent among registered voters.
