Most people agree that, given what we know now, Democrats will probably win the House, although Republicans have a chance to hold it, while the opposite is true of the Senate.
FiveThirtyEight, for instance, gives Democrats an 86.5 per cent chance to take the House, and Republicans an 82 per cent chance to hold the Senate.
But there's also the possibility that the "blue wave" could be even larger than it looks right now. If that's going to happen, it will take large turnout on the part of young people.
Which, if you know anything about turnout, you'd say isn't all that likely.
In Midterm elections, turnout among those under 30 is generally around 20 per cent.
But a new poll from the Harvard Kennedy School Institute of Politics shows that it's at least a possibility. The big headline on the poll is that 40 per cent of young people say they will "definitely vote."
Of course, some of them might be kidding themselves, but in previous iterations of that poll, the number was far smaller; in 2010, for instance, it was only 27 per cent.
And if they do turn out, the young people are going to turn out heavily against Republicans. Not only do they say they'll support Democrats by a 66 to 32 per cent margin, they can't stand President Donald Trump and they're liberal on policy issues.
Trump's job approval among young Americans stands at 26 per cent, with no statistical difference between all Americans under 30 and likely voters.
Eleven per cent reported that they are "sure to" re-elect the President in 2020 if he is on the ballot, 8 per cent indicate that there is "a good chance," 9 per cent say that it is "possible," 9 per cent say it is "unlikely," and 59 per cent say they "will never" vote for him.
The IOP poll, the 36th release in a series dating back to 2000, also indicates strong levels of support among young Americans under 30 for a federal jobs guarantee (56 per cent support, 63 per cent among likely voters), eliminating tuition and fees at public colleges and universities for students from families that make up to US$125,000 (56 per cent support, 62 per cent among likely voters), and for Single Payer Health Care (55 per cent support, 67 per cent among likely voters).
So the likely voters are more liberal than the young population overall. But that won't really matter if they don't get to the polls, and the truth is that we just don't know whether they will.
As Amy Gardner reports, young people are being deluged on social media with messages telling them how important it is to vote, from their peers and celebrities such as Taylor Swift, but we have no idea whether that pressure will produce results.
It may be working, but it's also possible that the messages have increased what pollsters call "social desirability bias," in which poll respondents give the socially acceptable answer regardless of what they actually think or will do. So it could be that many young people are saying they'll vote, but won't.
But I'd like to point to one other interesting finding here: that the likely vote for Trump in 2020 among the young is well below what it was in 2016. According to exit polls, Hillary Clinton beat Trump by 55 to 37 per cent among those under 30, but now you've already got 59 per cent saying they'll "never" vote for him, and the anti-Trump vote could go higher.
That matters not just for 2020, but beyond.
It might be tempting to think that young people are always liberal, but they aren't.
In 1984, for example, Ronald Reagan crushed Walter Mondale among young people by double digits, and in 1988 the scintillating George H.W. Bush won voters over 30 by 53 to 47 per cent.
Unless they change their minds in the next two years, young people could come through for the Democratic candidate in numbers comparable to 2008, when Barack Obama won young voters by more than 30 points.
Long term, that's a problem for the GOP, since once people establish a party identity in their youth, they tend to stick with it for their whole lives.
Which means that whether they turn out this year or not, Trump may be alienating an entire generation from the Republican Party.
