Trump mused last year about adopting the "Keep America Great" campaign slogan.

“How do you give up the greatest theme of all time with a new theme?” Trump said last year, of switching from “Make America Great Again” to “Keep America Great.” “If I lose, people are going to say what a mistake that was. But we’re not going to lose, so it’s not going to matter.”

Then coronavirus struck, the economy collapsed and racial strife enveloped the country. Amid the crises earlier this summer, the Trump campaign toyed with another rebranding. But "Keep America Great" hats are still selling for $25 a pop.

“You can buy all the domain names you want, but Joe Biden can’t ever buy a way out of his 47 years’ worth of failure in elected office,” Trump campaign spokesman Hogan Gidley said in response to the domain purchase.

Team Trump previously pulled something similar on Biden, purchasing the todosconbiden.com domain when Biden announced its Latino outreach program, dubbed “Todos Con Biden.”

The domain play was the Democrats' latest attempt at counterprogramming during the GOP event. Tonight, Biden will air a two-minute ad ahead of convention programming that includes a not-so-veiled clip of Trump struggling to walk down a ramp, followed by scenes of a vibrant Biden bicycling and jogging up stairs. It will run on all the major networks and over the weekend in battleground states.

The Biden campaign kicked off the week by announcing “Republicans for Biden,” a group led by Jeff Flake and including more than two dozen former members of Congress. The campaign rolled out a series of Republican endorsements during the week, including Justice Department and ethics appointees as well as former staffers for the late Sen. John McCain, 2012 GOP presidential nominee Mitt Romney and former President George W. Bush.
