Wrong, As Usual
All of the pundits, talking-heads, sources, VSP, ‘No Label’, Centrists, commentators, etc. were, as usual, wrong. You don’t get invited back if you know what you are talking about, which is why it is ‘news’ when Joe Biden finally told people that he really wasn’t running for President.
Joe Biden wasn’t launching ‘trial balloons’, it was the commentariat who were filling the lifting envelop with their significant output of hot air, but they didn’t have anyone in the basket.
If you weren’t paying attention in 2008, you missed the deal that Obama cut with Hillary that included the Secretary of State gig and non-interference in 2016, for Clinton support. Biden does not have access to the Obama organization because of the 2008 deal.
