I must say Joe is trying very hard to make me enthusiastic about him.
He's taking a page out of the (Canadian) Liberal Party playbook: Campaign from the left, govern from the center.
Also known as taking a page from the man who had Biden as VP.
Sounds reasonable, no?
Less reasonable than sticking to one's campaign promises. Doing otherwise can damage faith in democracy and arguably was a big part of what brought the US to the Trump point.
Governing as an incrementalist is reasonable. Governing as Obama did would would not be - Obama was not merely moderate in his aims, but moderate in what he was prepared to do to see them realised (understandable at the time due to a theory which had not yet been debunked - that voters, eventually, would punish Congressional Republicans for obstructionism). If Biden isn't prepared to play hardball and use executive power as a check on gridlock, and if he isn't prepared to stand up to the worst of the lobbyists, he risks falling into nastier version of most of the pitfalls of the Obama presidency.
I meant that it is not at all strange if Biden tries to emulate Obama's style. Of course I agree that if Biden becomes president and he tries to get Republicans on board like Obama did, he will only face stonewalling like Obama did, if anything worse stonewalling, so he should be more aggressive when it needs.
