Why does Biden claim he has "the most progressive record of anyone running"?

[Igel]

8. Not what he said.

Person versus record.

And there are various ways of interpreting it.

What's Warren done that's progressive? Ignore any non-progressive bits, any slip ups, just focus on "good things" in a lopsided manner.

Now, what's Biden done that's progressive? Make up the list in the same way.

Now, which list is longer, Warren's or Biden's?

I'm betting Biden's. Whatever he did in the '70s might easily be balanced by what he did in the 2010s.

Another completely and no more or less fair would be to look over all the accomplishments, assign a "progressive mark" to each and average them. On that ranking, Biden might be lower. Then again, it might be averaging 200 things over 45 years, where standards have been constantly changing, versus 3 in the last two years.

It's the kind of question that can only be met with a request for clarification or which ends in pointless wrangling.
