Anthony Zurcher: Democrats push deep into Trump heartland on historic night

In the Senate, Democrats flipped at least six seats, comfortably securing a majority.

Adam Hamilton won in Kansas - a state that last elected a Democrat to the Senate almost 100 years ago during the Great Depression.

James Talarico beat Republican Ken Paxton in Texas' Senate race, ending a 38-year Democratic losing streak in statewide elections there.

In South Carolina, Annie Andrews beat Darline Graham, who had been appointed to the seat after the death of her brother, Senator Lindsey Graham. Few analysts had that seat in play even a few months ago.

Five-term Republican Susan Collins conceded Maine's Senate election to Democrat Troy Jackson.
