Meanwhile Democratic Party leaders who paved the way for this Republican resurgence seem to view themselves as natural leaders in the fight against Trump, known as the "Resistance."
But are they up to the challenge?
Recall how badly they screwed up in 2016.
In capturing the Republican nomination, Trump became the most disliked presidential nominee in recent times.
This presented Democrats with an opportunity to not only keep the White House, but also make big gains in the House and Senate.
Instead Democrats rigged their own primaries, allowing Trump to face the second most-disliked nominee in recent times, Hillary Clinton.
Now the folks who helped pull this off want to lead the Resistance.
Democrats face an uphill fight in the 2018 elections.
In the Senate, Democrats must defend 23 seats, compared to just eight for Republicans. Meanwhile gerrymandered House districts continue to favor Republicans (who control most state legislatures, which draw the districts).
On top of this, the right-wing Koch network is expected to again pour in big money to back Republicans, including as much as $400 million ahead of the 2018 elections. In 2016, the Koch network targeted eight senate races, winning seven.
Still, it's possible to defeat the Kochs and Republicans, as President Obama's two terms show.
With the 2018 election on the horizon, the good news for Democrats is there's a groundswell of energy and anger, and a growing determination to take on Trump.
The bad news is the party's leaders are reluctant to unleash this tidal wave, possibly fearing they might be swept up in it themselves.
