Election night timeline: The Senate races to watch

Control of Congress is likely to come down to a handful of battleground races

The competitive map for control of the U.S. Senate has expanded considerably in the final days before Election Day. Here's a ranking of those competitive races from most likely to flip to least likely.

The Senate map unfolds from South Carolina at 7 p.m. ET through Alaska at midnight, with seven races in the toss-up column. The Hill’s Bill Sammon and Chris Stirewalt break down the projected vote shares and identify the contests that could determine control of the Senate.

The political landscape could be evident before most voters have dinner on Tuesday night. The earliest polls close at 6 p.m. Eastern in two red states, Indiana and Kentucky, where Democrats have contested some races.
