Mike Johnson helped Trump on January 6 - now he’s a threat to democracy

The Louisiana congressman Mike Johnson, whom Republicans in Congress elected as their speaker after more than three weeks of leaderless chaos, played a key role in Donald Trump’s attempts to subvert the results of the 2020 election.

Johnson amassed enough support to win the speakership because of his allegiance to Trumpian ideals, earning him the nickname on the far right of “Maga Mike”. A litmus test of sorts for the speakership was alignment with rightwing views, including believing in a stolen election, though the firebrand approach of failed speaker candidate Jim Jordan soured moderate members, despite his election-denying bonafides.

Johnson’s victory brought swift alarm from groups defending US democracy, which pointed to the prominent role Johnson will take in US politics before a crucial 2024 presidential election, and how election denialism is clearly no longer a fringe view in the Republican party.

Johnson was more involved than his predecessor Kevin McCarthy in efforts to overturn the 2020 election; McCarthy tolerated and often condoned election denialism and voted against certifying the 2020 vote, but didn’t go as far as the right-most flank.

Johnson, a lesser-known lawmaker, is perhaps most notable for his role in attempting to overturn Democratic president Joe Biden’s victory. His arguments against the votes, noting how states changed voting rules because of the pandemic, became a “narrow and lawyerly” way for members of Congress to object to the vote count on January 6, with Johnson as “the most important architect of the Electoral College objections”, the New York Times reported.

Johnson, who is a constitutional lawyer, also circulated an amicus brief – signed by more than 100 Republican lawmakers, including McCarthy – and filed it in a Texas court case to contest the results in four swing states.

A few days after the 2020 election, Johnson wrote on X, formerly Twitter: “I have just called President Trump to say this: ‘Stay strong and keep fighting, sir! The nation is depending upon your resolve. We must exhaust every available legal remedy to restore Americans’ trust in the fairness of our election system.’”

Johnson’s ascension shows the state of the mainstream Republican party today – their firm denial of the 2020 election and allegiance to Trump, said Gunner Ramer, the political director for the Republican Accountability Project. A more moderate Republican speaker nominee, the congressman Tom Emmer, failed to win over Trump and the far right, who saw him as a Republican in Name Only, or Rino.

Johnson’s win “speaks to the total disregard that the Republican party has had and still has for democratic institutions and the rule of law”, Ramer said. “Propping up someone like Mike Johnson should expose that fact within the Republican party.”

Stand Up America, a progressive advocacy group, called it a “dark day for American democracy”.

“Mike Johnson’s record of election denial and his attempts to overturn the will of the people make him totally unfit to be second in line to the presidency,” the group’s founder and president, Sean Eldridge, said. “Those who have spent years trying to undermine our democracy cannot be trusted to lead it.”

Already, Johnson and his supporters have made clear they don’t want to answer questions about the 2020 election. In a press conference Tuesday, when a reporter noted Johnson’s role and attempted to ask a question, she was met with boos and derision from Johnson and his allies.
