Biden's policies do not align with the tenets of communism or socialism.
Biden is not a communist or a socialist. None of Biden's policies support the elimination of private property or the nationalization of industries. As the New Yorker reports, Biden's career "has been distinguished mostly by careful centrism."
Many unreliable news outlets, such as Fox News, have accused Biden of having left-wing leanings. President Donald Trump and his supporters have made similar claims. During his unsuccessful attempt at re-election, Trump stated that "a victory for Joe Biden would be a win for China." In October, Marco Rubio, the Republican Senator for Florida—claimed on Fox News that “both in Caracas and Havana, the dictators [Nicolás Maduro and Raúl Castro respectively] are hoping that Joe Biden wins and Donald Trump loses. It is their only way forward.”
There is no evidence for these claims either. As PolitiFact has stated, "Republicans have used the term 'socialist' for decades to attack Democrats and their policies."
