Make no mistake: Democrats won by epic, sometimes historic margins across red and blue states, up and down ballots, obliterating almost everything President Trump, and a Republican Party remade wholly in his image, built over the past decade in American politics.

Why it matters: Trump and Republicans are left with a mostly white, mostly old House and Senate minority, confronting a younger, more diverse ascendant Democratic Party with power and margins it hasn't held in 18 years, since the dawn of the Obama era.

The results speak louder than any words we can write:

Democrats' big night gives them a chance to turn voter anger over high energy prices into legislative action and congressional oversight, but divisions within the party could complicate their plans.

Why it matters: This was an energy election.

Democrats will be able to take plenty of messaging votes on health care after their blowout wins Tuesday — but they'll face too many limits and internal disagreements to force all of the big policy changes they want.

Why it matters: They'll have a tough time repealing Medicaid cuts or restoring enhanced Affordable Care Act subsidies while President Trump is still in office, and their own divisions will hold them back on other issues.

• And Medicare for All? Last night gave the idea a big boost, but don't hold your breath.
