Democrats will control 53-54 seats in the Senate, not including Maine independent Angus King

Update, Wednesday Nov. 7, 1:50 p.m.: Earlier today, Nevada was called for the Republicans and Montana for the Democrats, leaving only North Dakota unresolved. We give it a 90 percent chance of going Democratic.

This means we expect the Democrats to have 54 seats in the next Senate, plus the likely addition of independent Angus King of Maine.
