In your world, Joe Biden was the modern day Abraham Lincoln, and the Russian propaganda firms are working overtime on HackerNews "smearing him".
In reality, Joe Biden was a career politician because he'd say whatever needed to be said to be elected at the time.
Being a career politician doesn’t mean anything positive or negative without further context. All that means is that you are winning elections.
You can be a career politician because you are popular and effective, or you can be a career politician because your political machine has done a good job of keeping you in power — or both.
Bernie Sanders has been in congress about as long as Susan Collins and they are definitely not the same people in terms of the integrity of their ideology and congressional voting record.
The rest is changing the subject - derailing and inflammatory.
