Washington (CNN)Congressional Democrats, benefiting from President Donald Trump's low approval ratings and historic trends working against the party in power, sit in the catbird seat in the battle for control, according to new House and Senate ratings from CNN.
The House, in which Democrats need a 24-seat pickup to win the majority they lost in 2010, looks more favorable at the moment -- largely due to the wide number of GOP-held seats in some level of jeopardy.
According to CNN ratings, 61 Republican seats are either toss-ups (15), leaning GOP (21) or likely GOP (25). Compare that to just 22 Democratic seats in any sort of jeopardy this fall and you begin to grasp the depth of Republican vulnerability.
