Former GOP judge Clark Erickson, appointed to assess disqualifying Donald Trump from Illinois primary ballot, believes Trump engaged in insurrection by trying to stay in office post-2020 election. However, Erickson thinks the decision should be left to courts, not the State Board of Elections. This poses a symbolic setback for Trump, facing challenges in 35 states and being barred from primaries in Colorado and Maine. In Illinois, the board's decision on Tuesday could impact Trump's candidacy, with potential for appeal to courts before the March 19 primary. The challenge is based on the 14th Amendment disqualifying officials who engaged in insurrection. Arguments and footage from the Capitol riot were presented, with Trump's lawyers denying the allegation and questioning the clause's applicability to the presidency.
