Uhhh, you are flat out wrong. They are basically the same thing[1]. Here is a link from CATO (a conservative outlet) talking about how the benefit of UBI is it would replace existing welfare programs[2]. Maybe try using google before making ridiculous claims.
> the 90's plan included Tort Reform which is need to lower costs
Tort reform was a straw man argument that was used by Republicans in a desperate attempt to explain why the ACA was not a 'conservative' policy. Pointing out small differences in policy details to try and explain away the origins of the policy is straight up dishonest. And just to be clear, tort reform was left out because it does not have a meaningful impact on health care costs[3]. Including it in the ACA would have been pointless and just added more complexity to an already complex piece of legislation. It was 100% the right thing to do.
> it simply gave the democrats grounds to then claim "it was not enough"
Largely because Republicans have continued to knee-cap the ACA at every turn. We tried to fix healthcare with a bipartisan policy, and you all threw a hissy-fit and decided to do everything in your power to make it fail. So I have zero sympathy with your single-payer fear mongering. The democrats shift towards stronger support for single payer was entirely in response to the shortcomings of the ACA, which largely happened due to Republican obstruction. You brought this on yourselves.
> Republican Party has more or less stayed the same or has shifted slightly to the left since 2000
I posted a link that was using data from a non-partisan research institute, and the conclusions of that research was that Republicans have been shifting rightward, even since 2000. Here is the link again[4]. Please show me credible non-partisan research to support your claim that the 'democrat party is pulled WIDELY to the left'. If you think the rise of Bernie Sanders and Elizabeth Warren some how proves your point, consider this: Bernie Sanders has been in politics since the 1980s. And as mentioned in my original post, his policy proposals would be considered center-left in any other time or in any other country. The only thing that has changed in the past 25 years in American politics is the complete take over of the Republican party by overzealous ultra right-wing anti-government partisans.
