The Colorado Supreme Court's decision to boot Donald Trump from the U.S. presidential ballot might just be the leading reason why they're doomed to fail

Colorado Supreme Court kicked former President Donald Trump off the state's presidential primary ballot.

John Avlon says the left-wing lawyers who brought the case ignored the consequences of the decision.

Avlon: It's hard to let Colorado boot a presidential candidate from the ballot because of the Constitution 's "insurrection clause" He says it's all cut and dried, spelled out in Section 3 of the 14th Amendment.

The Supreme Court heard oral arguments in a case challenging the state's ruling on whether to disqualify candidates for being an insurrectionist.

The Colorado decision would enable partisan officials to “disqualify political opponents by unilaterally declaring them insurrectionists” Landmark Legal Foundation says the justices were clearly concerned with the consequences of letting the state decision stand.
