evidence: Angered over COVID-19 mandates, distrust of Joe Biden's win in the 2020 presidential election and what he sees as overreaches of government authority, a Republican is looking to unseat Assembly Speaker Robin Vos in a rare Republican primary in District 63. And the challenger is situating himself with those who have gone beyond Vos to cast doubt on the results of the 2020 presidential election. [...] Vos isn’t afraid of losing his seat. He noted in a Monday evening phone interview that the last time he had a challenger in the Republican primary, when he was challenged by Bryn Biemeck in 2014, Vos still won 89.5% of the vote. [...] Steen, who ran unsuccessfully for Congress in 2018 in a Republican primary that was won by Bryan Steil, said he was at least partially inspired to run by Donald Trump. Both Vos and Steen are vocal Trump supporters.
