‘Wave versus the map’: Democratic control of Senate moves from preposterous to possible

The possibility that Democrats could win the Senate in 2018 seemed preposterous a year ago given President Trump’s stunning victory and the basic math facing a party defending three times as many seats as Republicans in November’s midterm elections.

Not anymore. The debate has grown over Democrats’ chances of capturing control of the agenda and holding power over Trump’s nominations, including potential vacancies on the Supreme Court.

The dispute pits the practitioners of big data against those who also scout candidates and measure broader political atmosphere to make their bets. Both sides agree Democrats face a narrow path to gain two seats needed to reclaim the majority — but there is a debate over just how narrow. CONT.
