You should reread his speeches. He didn’t lie about being a progressive. He was openly a centrist.
He never promised single-payer health care or a public option. He promised to stop insurance companies from excluding people with preexisting conditions, which he did.
He never promised to end all the wars. He promised to withdraw troops from Iraq and send more troops to Afghanistan, which he did.
And he didn’t say anything at all about taxing the rich or helping unions.
Just for comparison, the Feds indicted some random person for selling pirated TV shows in 2019 and didn’t get a conviction until this month. That’s five years, and the SCOTUS wasn’t even helping him drag the case out.
Federal cases take a long time when defendants insist on going to trial and dragging things out.
