The primary and General Election campaigns

There are three main parts to every election year. The primaries, where delegates to the party's quadrennial convention are selected, the conventions themselves, and the Fall General election.

Post-election litigation and presidential transition

The election was held on November 3, followed by a period of election litigation and attempts to overturn the election by the Trump campaign. There were 6 states targeted for voter fraud lawsuits: Arizona, Georgia, Michigan, Nevada, Pennsylvania, and Wisconsin, all battleground states in the 2020 presidential election.

Out of 55 cases, 14 were dropped, 30 were dismissed, 6 ruled against, and 5 pending ongoing trial or appeal.

Texas v. Pennsylvania

On December 8, 2020, Texas Attorney General Ken Paxton sued the states of Georgia, Michigan, Pennsylvania, and Wisconsin in order to invalidate the results of the presidential election in those states. The lawsuit was filed with the U.S. Supreme Court due to their jurisdiction over state disputes. Donald Trump referred to this case at "the big one" and 100 Republican representatives supported Texas. However, due to the lack of Article III standing, the case was dismissed by the Supreme Court.

On January 7, 2021, President Trump formally conceded the election after the Electoral College vote count.
