Donald Trump is gaining on Kamala Harris in the polls. I have some theories why | Robert Reich

Trump, widely regarded as the sleaziest person to ever run for president, is leading or tied with Harris in crucial swing states

With less than 40 days until election day, how can it be that Trump has taken a small lead in Arizona and Georgia - two swing states he lost to Biden in 2020? How can he be narrowly leading Harris in the swing state of North Carolina? How can he now be essentially tied with her in the other key swing states of Michigan and Wisconsin?

More generally, how can Trump have chiseled away Harris's advantage from early August? How is it possible that more voters appear to view Trump favorably now than they did several months ago when he was in the race against Biden?
