Trump, the guy with the BEST memory, forgot that he ran for the US presidency in 2000.
Donald Trump presidential campaign, 2000
Trump officially ended his campaign on the February 14, 2000 airing of The Today Show. Though he believed he could still win the Reform Party presidential nomination, he felt the party was too dysfunctional to support his campaign and enable a win in the general election.
This is another example of why we should never, ever believe Trump.
Just a reminder: Barack Obama won the Presidency on his ACTUAL first try.
