Democrats will control the Senate following the presidential inauguration, after sweeping both runoff elections in Georgia.

Getting at the “red mirage” idea, if we don’t get Atlanta and big GA burbs, and some major blue areas of Wisconsin and Pennsylvania it’s easy to see Trump’s lead holding for now or staying closer than they should end up. Same for GA senate races Charlie 

Meanwhile, AP just called Alabama Senate race for Republican Tommy Tuberville. So each party has flipped their easiest seat, and the Senate is back where it started at the beginning of the night.

Democrats got their first big flip of the night, with John Hickenlooper knocking off Republican Sen Cory Gardner in Colorado. Necessary but not sufficient for a majority flip

Hey Charlie! Polls closed at 8 p.m. The AP has already called the state for Biden and Sen. Booker. They were never in question

New Hampshire too, which was an underrated squeaker in 2016. If the Democrats hadn't defeated Kelly Ayotte, Trump's Obamacare repeal might have passed the Senate.

One note about the travel to Georgia: obviously it's being done in an effort to flip the state for Biden. But it's also hugely important for the Senate races. The special election there is almost certain to go to a runoff. But the race between Republican Sen. David Perdue and Dem Jon Ossoff is going to be really close. Dems had expressed some confidence to me in Ossoff's path to 50% of the vote and avoiding a Jan runoff. But he'd need a pretty strong W from Biden to do that. Senate Dems were ecstatic that Biden, Harris and Obama visited the state in the closing stretch

Charlie, Look no further than who's shown up there in the last week! Obama, Biden, Harris... and Trump. It's clearly a battleground. And the stakes are so high: Two Senate races, a state House that could flip, several competitive House races.

Charlie and PA, MI, OH & IL are on track to lose a seat!

The Texas Senate race is one to keep an eye on. Beto O'Rourke's near miss in 2018 was a pretty good sign of how the state was changing, but Cornyn has proved less vulnerable than some of the other GOP incumbents this year... although Democrats feel like that race broke pretty late in MJ Hegar's favor. If Cornyn goes down tonight, that means Dems are probably going to have a really, really strong night

A competitive presidential race, tons of hot House races, a competitive Senate race, state leg races...what is going on there?

How have we gone so long without talking about Texas?

Stephanie Meanwhile, Collins goes into Election Night never revealing whether she voted for Trump for a second term.

To your point about Maine's blue tilt, James, the Maine Democratic Party even paid for lawn signs that say "TRUMP COLLINS 2020" to try and tie her to the president.

So if Susan Collins loses tonight, is New England completely wiped out of Republicans in Congress?

If Collins can hang on, Democrats will have a much, much tougher time winning the Senate back

Charlie That ad is a perfect example of how Collins has tried to hang on in Maine despite the state's blue tilt. She's facing easily the toughest reelection of her career, and her message has been that she's delivered for the state and never "Gone Washington," basically arguing that handing over this seat to someone less experienced would result in big losses.

It's a really interesting contrast with what Democrats have done. Their ads visually look similar, but the super PAC Senate Majority PAC has been spending weeks running 15-second TV ads where Maine voters saying they used to support Collins, but give various reasons for why the thinks she's changed and they can't support her anymore

Speaking of the Susan Collins Senate race in Maine, here's one of her ads. The county they are referring to is her native Aroostook County https://youtu.be/TC0aI-jWAgU

Greetings, Charlie, from about 20 feet away from you here in the socially distanced POLITICO newsroom in Arlington. I'm going to be watching for what we can say at the end of the night about the presidential race and the battle for the Senate. We've been talking about the three different outcomes tonight without decisions in some key states : A Biden win (possible), a Trump win (less possible, based on the electoral math) and the still-undecided conclusion (probably most likely). But there are varying degrees of "too early to call": Scenarios in which we probably know who won, which would make it more difficult for the trailing candidate to argue that the process moving forward is unfair, or one in which there's real drama about the continued vote count in the states still working their way through mail and provisional ballots. That outcome could get very messy, but we shouldn't assume solely ending the night without a winner will necessarily be that messy.

Happy Election Day! No surprise, I'm watching the battle for Senate control. Republicans go into the night with a 53-47 majority. There are a huge number of potentially competitive races. The likeliest flip for Republicans is Alabama. The likeliest flips for Democrats are Colorado and Arizona, followed by tight races in Maine, North Carolina and Iowa. If Democrats can flip two of those three, they'll likely win back the majority six years after losing it. There are also races in Montana, South Carolina, Kansas, Alaska and Texas that could flip if Democrats are having a REALLY good night. And if Republicans are having a really strong night, Michigan is their next best opportunity. The possibilities are a little dizzying.

But one thing to keep a close eye on: Georgia. Two races in that state, and one is almost certain to head to a January 5 runoff, while the other is going to be extremely close and could potentially also go to a runoff. So the majority could be won tonight. Or... it could be won in January.

Hello from Boston! It's hard to believe the election is finally here. I have my eye on the battle for the Senate. One race where Democrats are hoping to flip a seat blue: Sen. Susan Collins up in Maine. She's facing a tough challenge from Democrat Sara Gideon, and the state's new ranked-choice voting structure puts the race in new territory.
