Biden might be to the left of Republican party (barely - his voting history is pretty much in line with current Republican values) but there is really nothing 'left wing' about free education for poor kids with good grades as it is the norm in numerous countries which have right wing governments and are considered generally right wing. The US is the only country in the entire world with anywhere close to that extent of wildly unaffordable college tuition.

Moreover he might pay lip service to some of the popular 'left' causes right now, because he's in a primary, but his voting record says otherwise. Again, taxes for the top brackets are already about the lowest in history by tens of percent, with many Republican governments of the past implementing much higher tax brackets. Tax loopholes now make upper bracket taxes basically unpayable and as he's said nothing about closing those loopholes I'm assuming the rich won't get taxed less under him anyway.
