Election Day 2024: Kamala Harris addresses the nation after election loss

George W. Bush weighed in on the election results on Wednesday morning, congratulating Trump and thanking President Biden and VP Harris for their service.

"I congratulate President Trump on his election as 47th President of the United States of America, as well as Vice President-elect J.D. Vance and their families.

I also thank President Biden and Vice President Harris for their service to our country.

The strong turnout in this election is a sign of the health of our republic and the strength of our democratic institutions. Laura and I are grateful to the election officials, poll workers, and volunteers who oversaw a free, fair, safe, and secure election."

Former President Donald Trump and Vice President Kamala Harris have allegedly not connected yet as of early this morning, Trump's senior adviser Jason Miller said on ABC News' Good Morning America.

"As of the last time I spoke with President Trump, they had not connected, but we'll see what happens today," Miller said, going on to stress the message of unity.

"I think what President Trump said last night when he's up there on the stage was that he wants to heal the country. This is the time when we put aside the political divisions. We bring Democrats, Republicans, people who aren't necessarily even involved with politics together," Miller said.

Over the next few months, ABC News and 538 will do a lot of analysis to figure out how exactly Trump won. He may be, after all, only the second Republican presidential candidate since 1992 to win the national popular vote. That warrants not only introspection among Democrats, but a lot of quality analysis, too. And Trump's sweep of the swing states - while not surprising - also represents a new high-water mark for his electoral success.

While control of the House is still up in the air, should it fall into the GOP column, Trump would begin his second presidency once again with a unified government behind him, and we'd get an immediate sense of how his approach to governance may have changed and how closely Republicans fall in line behind him. I think it's worth reminding ourselves that another Trump candidacy, let alone presidency, was far from a given at the end of his last term.

Trump's first presidency was marked by some growing pains between his outsider, populist style and more establishment Republicans in Congress, particularly in the Senate. That caused some fits and starts in implementing an agenda - with Republicans sometimes seeming to govern in spite of Trump as much as with him or under his leadership. Even the end of his presidency was marked by Congress scrambling back into session to override his veto of a bipartisan defense policy bill on New Year's Day 2021.

Check that date - it was just a few days before the Jan. 6 insurrection. After the events of Jan. 6, seven GOP senators voted to impeach the former president, and others - like Senate Majority Leader Mitch McConnell - at least flirted with it. While it wasn't a full-throated rebuke from the party on paper, it did feel like many Republicans in Congress were eager to close the door on Trump's chapter of the GOP. That was still the narrative after the party's underwhelming 2022 midterms, when Trump's endorsed candidates seemed to flounder. The party at that time seemed to be facing a choice about its future.

Still, as soon as the 2024 Republican primaries started, it seemed that Republicans resigned themselves to making Trump their standard-bearer once again. Even as a presidential candidate, he held significant sway over the GOP agenda, like when he tanked a bipartisan border deal early this year. And as we heard hints of in his speech tonight, Trump is almost certainly going to take full credit for what looks to be a great election cycle for Republicans. His standing as party leader may translate better to Congress this time around, between his experience in the job and what looks to be a larger Senate GOP majority. After tonight, it feels like it's Trump's GOP, and we're all just living in it.
