First, I think you should understand that I am not someone who believes everything I hear. Unlike many of the right-wingers on this board, who seem to believe whatever Trump of the Faux News echo chamber spews. So, never have I said that I think Biden never lies, nor do I take what he says without a grain of salt.
The major difference here: Biden's lies are, when compared to Trump, are few and far between. He doesn't lie about major things. You may not like that, but nor do I. But, I understand the media game very well. And I understand the nuance. It isn't black or white, but Biden doesn't also make up shit like Trump. So, if we're looking at someones true colours, Biden is significantly more trustworthy than Trump on any day of the week, and twice on Sunday.
