Democrats now lead in enough states to take back the Senate so long as Clinton holds on to her large lead. If the favorites in the polls win, the Democrats would flip and pick up the seats in Illinois, Indiana, New Hampshire, Pennsylvania and Wisconsin. Republicans would pick up Nevada and hold onto Florida, North Carolina and Ohio. Of course, many of these races are close, and theres plenty of time before Election Day. The fight for the Senate isnt over by a long shot. Republicans and Trump or Republicans without Trump could rebound.
On the other hand, Democrats have a lot more pickup opportunities in the Senate than Republicans do, such as in North Carolina, where the race has been tightening. If Trumps numbers fall even further or Republican Senate candidates fade down the stretch, as some did in 2012, the Senate picture may become even gloomier for the GOP.
