Although Justin Amash’s Tea Party convictions and public breakup with the Republican Party has given him a higher profile than the usual 40-year-old congressman, even he seems to know that his Libertarian Party bid for president is a longshot.

But Amash is differentiated by factors that stand out in 2020: he’s a fiscally conservative, pro-life libertarian without a single whiff of a sexual assault or financial scandal in his midst. For Republicans disgusted by President Trump’s multitrillion-dollar deficits and slew of groping allegations, Amash should provide an obvious protest vote against the Republican Party.
