I don't care about his voting record, the guy's been in politics for decades. Go back far enough and even Obama
opposed gay marriage. Even Bernie Sanders has some
spotty moments in regard to his support. At the end of the day long term politicians have to bend to modern trends. Someone who's been in politics for longer than most of us have been alive are bound to flip flop on issues depending on public opinion. Comparing US politics left vs right to say, Europe doesn't really work as you need to compare the actual political climate to itself. Things like basic social policies already in place in Europe aren't in the US yet, so while the plans outlined by Biden, Obama etc might be center or right by European standards claiming that they're "moderates" is pointless as in their own climate they're clearly left.
15 an hour federal min wage
Free 2 years college for those in families making less than 125k.
Debt relief for existing student loans.
Creation of a "buy in" US healthcare insurance. Effectively Medicare "if you want it". Not M4A but a step in that direction.
Progressive tax plan that puts pressure on the rich instead of Trump tax cuts.
Investing heavily in public education, both in funding and teacher pay.
Government support for worker's unions.
Focus on clean energy and not claiming that windmills cause cancer.
Support for fighting climate change that doesn't imply that it is a Chinese hoax.
Supporting LGBT+ equality and fighting the Xenophobia championed by Trump.
I mostly linked to Joe's website which is basically just propaganda and really needs a tl;dr version, but it's a good starting point to grasp the basics of what he plans to do. Once again no, he's not Bernie nor is he quite as left as a lot of people want. But his plan will push us closer to where we want to go, and as we all just watched more than 70 million people voted for Trump, so it's important to understand that unless you want to lose every election for being too extreme it's okay to take baby steps.
We don't really know which of these policies will actually happen. The Republicans will likely control the senate, so he's going to have an uphill battle in a lot of ways. Maybe it will just end similarly to Obama where many of his plans or ideals will end up half-assed due to government fighting.
Idk man, I'll take it over what we just dealt with over the last 4 years. Even if there's only a 10% chance of any of these things being focused on it's better than the 0% chance of it happening under Trump. Biden isn't the hero we want, but he's the one we need right now.
