The Supreme Court‘s pending decision on whether former President Donald Trump should be on Colorado‘s Republican primary ballot makes this Super Tuesday unlike any other.

With Trump’s legal problems upending this election season more broadly, the Supreme Court’s decision, which could be announced on Monday morning, could similarly upend Super Tuesday’s primary results in Colorado and Maine before Illinois votes later this month.

Colorado Republicans and unaffiliated voters have been able to cast a ballot for Trump. But if the Supreme Court decides in Trump v. Anderson that the former president was ineligible to be on Colorado’s ballot, pursuant to the Constitution‘s 14th Amendment insurrectionist clause, those votes will not be counted, and Trump will not be on the state’s ballot for November’s general election, according to the Colorado Republican Party.

Colorado Republican Party Chairman Dave Williams explained that if the Supreme Court does decide against Trump, the Colorado GOP will “ignore” the state’s Super Tuesday primary results and depend, instead, on the state party’s caucuses from March 7-9 and state Assembly on April 7 to allocate its 37 Republican National Convention delegates.
