Senate Democrats have a big problem. Historically, Senate candidates struggle where their party's president is the least popular. And, as Gallup's 2013 state approval-rating averages show, President Obama is very, very unpopular in the states Democrats have to defend in the 2014 elections.
One look at Obama's state-by-state approval rating averages ought to send a shiver through the ranks of Senate Democrats.
Republicans need to capture six seats to win control of the Senate, and Democrats have to defend five deep-red states—Arkansas, Alaska, Montana, South Dakota, and West Virginia—where Obama's approval rating was at or below 35 percent in 2013, according to Gallup's 2013 polling averages. The president was also far underwater in another two Democratic-held states he lost in 2012, Louisiana (40 percent) and North Carolina (43 percent), as well as purple-tinged Colorado and Iowa (42 percent), which Obama won.
In the past 10 years, just nine senators of the president's party have won elections where presidential approval slips below the national average, according to a review of exit polls and election results since 2004.
