Biden now has launched a minute long nothingburger TV ad. A nothingburger candidate produces as expected. No mention of all those fat-cat fundraisers. Puffery instead. Swinging off Obama's popularity. Touting Romneycare as if it's the best the nation can do for its citizens.
It does not say "Nothing will fundamentally change." That is for the moneyed fundraiser crowd, to reassure them.
The Biden thing says Trump has to be ousted, something the Bernie and Warren supporters understand too, only they've better thinking beyond that simple truth.
Tired TV hucksterism will not oust Trump. The truth is that Bernie will induce a massive turnout of the young and those believing the current system, though entrenched, can be bested. Biden? He is the entrenched system personified. And his turnout would reflect that.
A ho-hum turnout will not cut it. Trump's base is rabidly being aimed to turn out in droves, and the Democratic Party needs to energize a bigger turnout to win the Presidency, while also preforming well down-ticket.
As Trump characterized "low energy Jeb," who faded, "low energy Joe" has support of the Beast, bankers and lobbyists, but so does Trump.
Bernie mirrors the will of the people, being mainstream in that his policy positions are what polling shows the great majority of the people want from government. They want progress, not more of the same.
______________UPDATE_____________
Another video. What you see is what you get from someone who has spent thirty unimpressive years in DC, thirty years in the Senate; who is somebody telling you what cannot be done, (besides money-sucking trillion dollar regime change war on the other side of the globe). Somebody patronizingly throwing cold water on Green New Deal hopes, on idealism, with false "pragmatism." With ho-hum rhetoric. With blaming the Republicans for what is bipartisan sloth. This is done to the young, by one of Joe Biden's strongest allies, who is not even a tepid Kamala Harris Dem. It is an attitude thing which rings as the antithesis of responsiveness to needs and wants of the nation. It is entrenched beltway thinking, so no surprise we see a Biden endorsee, a multimillionaire for multimillionaires talking down to the next generation which will have to suffer the consequences of output from cramped, unimaginative minds beholden to the 1% and indeed, a part of the 1% and thinking of what benefits the 1%. Hello Diane. Hello Joe. Identical but for being of opposite genders. Same old, same old.
