In as much as Sanders is suggesting a return to the roots of government of, by and for the people;
In as much as Sanders is arguing that a movement must be grown from that root that changes national governance or little will be accomplished;

Sander's message is, consequently most certainly 'radical'.

The problem, of course, is that most daily experience of the American people can be captured in 1200 words, and the most colloquial meanings of those words.

In that world "radical" is a bad word. In that world, "democratic socialism", is missing from the lexicon, because it of the number of syllables, and similar sound to Soviet Socialism, it is scary to people with limited vocabulary.

Neither of which is what we have, the U.S. is a corporacy.

Since the Am Revolution across the world we've seen attempted empires, a variety of totalitarian putsch to dictatorships, and the rise of neo-feudalism via plutocrats and oligarchs.

Human nature contains peculiarities sufficient to always leave the existence of democracy an open question.

As Franklin responded when asked about the form of American government, "We have a Republic, if we can preserve it."

of course even with that, it was never one man, one woman one vote and whoever wins the most popular votes wins the election.

Blacks, women and poor white men couldn't vote, that began to change with Jackson's election and then after the Civil War, even then it has been a continuous struggle in one form or another.

Electors based on the popular vote sometimes winner take all in the states would go on to elect a President, not the people.

However in the mid to late 19th century corporate supremacy began to take hold, the latest manifestation of that is the Citizens United decision.

Oligarchs and mega-corporations yank the government's chains, not "We the People" and anyone proposing to give power to the people as Bernie is doing, is most definitely considered a radical by those established powers whether it's the less than 1%, mega-corporations with their authoritarian hierarchy or their corporate media mouthpieces.

Both just take a little consideration to get beyond knee-jerk reactions to fear of knee-cappers.

He's AWESOME, dude!

What is extreme nd radical is the obscene concentration of wealth and power that has developed over the last 30 years.

you want him to be all that in radical.

make up your mind
