Trump's victory in the White House is being called the “greatest political comeback in American history.”

From political pariah to presidency.

Four years after Americans drove then-President Trump from the White House and he left Washington in political disgrace two months later after trying to overturn his election defeat, they are sending him back to 1600 Pennsylvania Avenue.

“It's a political victory the likes of which our country has never seen before,” Trump said in his celebratory speech early Wednesday morning, referencing his convincing electoral and popular vote victory over Vice President Kamala Harris.

And his running mate, Sen. JD Vance of Ohio, called Trump's victory “the greatest political comeback in American history.”

In his victory speech, Trump proclaimed that his political movement was one that “no one has ever seen before…this is the greatest political movement of all time.”

For an undisciplined candidate known for his exaggerations, Tuesday's election results appeared to prove Trump right.

“This is a historic political realignment,” said veteran Republican strategist Ryan Williams.

Williams argued that Trump has “essentially discarded the coalition that Republicans have put together over the last few decades and strengthened the voting blocs that he thought he could align with.”

“He simply expanded the party in a way that no other candidate has done before. And I think that's why the poll didn't do that, because he changed the makeup of the electorate so radically,” Williams emphasized.

For Trump, the 2024 campaign was a grueling two-year marathon. He announced his candidacy at his Mar-a-Lago club in South Florida a few days after the 2022 midterm elections.

And he launched his campaign amid criticism from many in his party that he was partly responsible for the Republicans' weak performance in the midterm elections.

But after a slow start, the former president eventually easily defeated a field of Republican primary opponents – which briefly grew to over a dozen contenders last year – as he topped the Republican presidential primary earlier this year.

Trump, who has been indicted in four separate criminal cases, saw his support and fundraising surge late this spring after making history as the first former or sitting president to be convicted of crimes.

A month later, President Biden suffered a major setback after a disastrous anti-Trump debate in late June reignited long-standing questions about whether the 81-year-old president was physically and mentally ready for another four grueling years in the White House – and sparked calls within his own party for his resignation.

Trump's lead in the polls over Biden widened, and the former president was further strengthened politically after surviving an attempt on his life at a rally in Butler, Pennsylvania, two days before the start of the Republican National Convention in July.

But the race was suddenly upended days later when Biden ended his re-election bid and endorsed his running mate. Democrats quickly coalesced around Harris, and her fundraising increased as her poll numbers soared.

Harris' honeymoon lasted until the Democratic National Convention in late August and into September, when most pundits declared her the winner of the only presidential debate between her and Trump.

But as the calendar shifted from September to October, Trump appeared to be regaining his footing, and public opinion polls suggested the former president was gaining momentum.

Longtime GOP strategist David Kochel noted that “we’re still in a country where you’re 70% on the wrong track. Voters wanted to change who was in the White House.”

Kochel, a veteran of numerous Republican presidential campaigns, noted that while Harris “has breathed some life and some enthusiasm into the campaign, the fundamentals haven’t changed. People are dissatisfied with the economy. You think the country is going in the wrong direction.” And you wanted to change something, and it turns out Trump won the change argument.

“And he also ran a very effective swing state campaign with effective advertising that hurt her,” Kochel added.

Williams also praised the Trump campaign, saying they “had a strategy and stuck with it. They basically just said let's choose men…they reinforced it with men…they had a consistent strategy for it and it worked.”

And Williams argued that Harris “basically took the Hillary Clinton playbook from 2016, copied it and made it worse.”

And both strategists emphasized that Trump was able to overcome his many misrepresentations and controversial comments.

“We pay so much attention to the crazy things Trump says. All the stuff that people find inappropriate. “It doesn’t matter,” argued Kochel. “He had a better strategy and an environment that was in his favor.”

And Williams emphasized that Trump “understands the electorate and connects with people in a way that no other politician does. He just talks off the cuff in his own way, and even though he tells a lot of untruths, he is viewed as genuine because he is not a high-profile politician.
