Not quite accurate. I see The Big Guy as the love child of Carter,McGovern and Saul Alinsky.
The Big Guy is a partisan Democrat, and partisan Democrats have changed. In contrast to Obama and the Clintons, Biden didn’t go through anything approaching a radical phase. He just says — or struggles to say — what his handlers tell him. You can view his administration as a mixture of McGovern and Alinsky, but that’s because of his programmers. The Jimmy Carter is all Biden’s own.
