Democrat Senate candidates in battleground states will have a difficult time overcoming President Joe Biden’s underwater approval rating.

Biden’s average approval rating in seven of the top Senate swing states is underwater by an average of 15 points, a key midterm election bellwether metric Democrats fear come November 8.

According to Civiqs, Biden has a negative approval rating in the following swing states: Arizona (-18), Georgia (-20), Nevada (-17), New Hampshire (-1), Ohio (-24), Pennsylvania (-13), and Wisconsin (-13). Not included in the calculation are Biden’s approval ratings in Florida (-15), Colorado (-8), or Alaska (-21).
