People can't simultaneously say Dems want to "change nothing" but at the same time say their agenda is to "implement radical far left policies."
no one is saying both of those 2 things. Republicans are saying they want to implement radical far left policies. But this indicates they have no idea what policies biden actually supports and only get their info from right wing sources. People who actually look at what the dem's want to do (as well as the dems themselves) say they want to "change nothing". Biden said it himself at fundraiser for high dollar donors.
The big one is expanding government healthcare.
Biden's plan is to slightly expand obamacare. At best this will get more people onto healthcare (which is a net positive). but his plan does not include getting everyone onto healthcare and does not resolve the massive price gouging that is going on. It fundamentally does not fix the problems.
Most Dems also want to end or mitigate Trump's border policies.
What does this even mean? Obama deported record numbers of people. Trump made it a more noticeable issue, but the dems agree with the republicans on border issues for the most part. I mean the cages trump locked children in, were built by obama to lock children in.
They want to move toward renewable energy (the Green New Deal is very unpopular though and is not a serious goal as written).
The environment is one of the very few places Biden has been willing to shift a bit.
And they want to rewrite the tax code so as to tax the 1% and corporations more.
Have you actually looked into that though? Biden actually moved up the line where the promises of no new taxes were. Hilary was promising not to increase taxes on people making less that $100,000. Biden moved that to $400,000. Their plan is to roll back trump's tax cuts, but i haven't seen any evidence they are willing to go much further than that.
Whether or not any of this gets done will largely depend on how obstructionist the GOP Senate wants to be, but it's not true they want to "fundamentally change nothing."
Basically none of what you have described is a fundamental change (except the environment). most of it is a return to obama era policies. IE, the failed policies that caused people to vote for trump in the 1st place.
Some are saying they want to expand the Court or add Congressional seats lol is that nothing?
Some are saying that. Biden repeatedly refused to comment on it. So there is no evidence Biden would even consider that.
