There is an argument I have heard that I do not fully discount which is that Joe Biden understands very closely what Obama is on about and is attempting to undermine his presidency and lose him re-election. Biden is not the fool he has apparently become and this kind of statement is not an asset to the Obama campaign, that’s for sure.

Here is how the story starts:

Joe Biden on Tuesday said the middle class ‘has been buried the last four years,’ words Republicans trumpeted as evidence that even President Obama’s veep doesn’t believe the incumbent administration has been good for the country.

There was plenty of advice to Obama to replace Biden with Hillary which he did not do, possibly because of the fear he had of what Biden might say if actually free to do so.
