During its exhilarating convention, the Democratic Party rebranded itself. It was impossible to miss the sea of American flags, which everyone periodically waved in unison, or the loud chants of “USA! USA!”

It was impossible to miss the frequent paeans to FREEDOM and the signs in the audience emblazoned with the word FREEDOM.

As the brilliant writer Anand Girihadaras wrote on his blog “The Ink,” Democrats reclaimed five words that had been captured by the Republicans:

Freedom. Patriotism. Family. Masculinity. Normalcy.

Governor Tim Walz was a key figure in exemplifying these words. A guy animated by love of family. A coach. A hunter (who favors common-sense gun control). A member of the National Guard for 24 years. A guy.

Kamala Harris, Walz, and others focused on Freedom: the freedom to make your own healthcare decisions, the freedom that comes from knowing that your child will not be shot dead in school, the freedom to afford a home, the freedom to vote. Walz said, on more than one occasion, that the government should not insert itself into your doctors’ office or your bedroom. He repeatedly invoked what he described as a small-town virtue: “Mind Your Own Damn Business.”

Harris and Walz deliberately snatched those words away from the Republicans and claimed them as their own.

At the same time, they doubled down on criticizing Trump for his affinity for tyrants, like Putin. In their display of dignity and patriotism, they contrasted their party with Trump’s unhinged rants and childish personal insults. They emphasized the importance of telling the truth, as Trump tweeted that the next round of a Trump administration”would be great for women and reproductive rights.”

And they showcased JOY, as they laughed and danced in the aisles. The contrast was especially sharp during the states’ roll call vote: Republicans announced their votes to polite applause; Democrats announced their votes to music and dancing and flashing lights. Harris radiated joy, with her vivacious smile and her celebrated laugh. Trump evoked fear, frightening images of a nation in decline, divisesiveness. Which America do you want to live in?

The Republicans spoke wistfully about turning back the clock to a mythical time when America was “great.” An era of white male supremacy? An era of Christian dominance? The Democrats spoke hopefully about a better future, where everyone has the opportunity to live a decent life. The past or the future. Your choice.

The biggest contrast was the difference in the delegates themselves. The Republicans were, with minor variations, the party of white people. The Democrats overflowed with ethic and racial diversity.

Which party is the past? Which is the future?
