Biden is not even remotely a communist or a Marxist. What makes no sense is that anyone would actually think this. Both Republican and Democratic parties are strongly tied to industry concerns, and live off 'donations' from corporate lobbyists.
For just one example. Trump lowered the corporate tax rate to a flat 21%. Biden intends to raise it to a flat 28%. Is that your definition of Communist, increasing the corporate tax rate by 7%? Have no concerns, I'm sure numerous tax loopholes will quickly follow the raise in corporate tax rate.
I think Trump is closer to a failed Franco than any Roman Emperor. The wiki page on Franco has some interesting statements.
"Although Franco himself was previously known for not being very devout, his regime often used religion as a means to increase its popularity"
"The consistent points in Francoism included above all authoritarianism, Anti-Communism, Spanish nationalism, national Catholicism, monarchism, militarism, national conservatism, anti-Masonry, anti-Catalanism, pan-Hispanism, and anti-liberalism"
"Francoist Spain presented the conflict as a crusade against Bolshevism in defence of Christian civilization"
"Franco was also the focus of a personality cult, which taught that he had been sent by Divine Providence to save the country from chaos and poverty."
"Francoism professed a strong devotion to militarism, hypermasculinity and the traditional role of women in society."
