Throughout his decades-long career, history lover and travel guru Rick Steves has opted to stay away from political commentary.

But with less than a week until Tuesday's presidential election, Steves used a Friday interview on Boston Public Radio to argue that the question over whether Joe Biden or Donald Trump should lead the nation is “more fundamental that partisan politics.”

"I just think our democratic norms are under attack,” he explained. “When one party has decided it's going to cling to its ways even though there’s a generational, demographic shift that puts it in a perpetual minority, then the only way that it can stay in power is to subvert these norms and depress the vote.”

And while Steves admitted that a Biden win would be “very expensive” for him as a well-off businessperson, he said he’s deeply worried to see politicians, as he describes it, operating with “frankly… the same playbook that autocrats and tyrants and fascists 100 years ago did in Europe."
