Democratic presidential nominee Hillary Clinton is clinging to a slim lead and the party’s Senate candidates are fighting to grab control of the chamber. Enter President Barack Obama, poised to serve the role of his party’s campaign closer.

Aides say he will be on the trail at least twice a week until voters go to the polls on Nov. 8. The timing of his increased presence on the trail is a calculation that deploying Obama so late could help motivate voters that helped him win two terms.
