H.L. Mencken said “nobody ever went broke underestimating the intelligence of the American people.” Now Hillary Clinton is challenging the Mencken postulate with a campaign that you have to be a moron to believe.

Is it possible that anyone, anywhere can believe that Hillary is like the “average” American? Toting her own baggage? Flying coach? Loading up the van? Driving to Iowa?

Can anyone really believe that this woman who travels by private plane every chance she gets, earns $200,000 for a one hour speech, $14 million for a book, and benefits from hundreds of millions raised by her foundation is a true champion of income equality?

Hillary’s campaign, so far, is an insult to the intelligence of the American people. She must think we are totally stupid. In effect, she has set an entry bar to her campaign: Total credulity.

Her campaign is so obviously based on a gimmick that is wholly inappropriate to the real person that one must be ashamed to believe it. To fall for her line, you have to be so totally out of it that you probably never vote.

It is easy to see that this is a campaign designed by commercial media people, accustomed to selling Coca Cola where intellect has nothing to do with the sales pitch.

Obviously, Hillary has launched before she is ready with a message. Her current pitch is the default messaging of a campaign with no direction or issues. She announced, not because she is up to it, but because her lawyers and accountants told her she could only pay her staff if she became a candidate and her people said they had had enough of working from home and from Starbucks without pay.

Rather than ad lib — always a disaster for her — she chose to stay with cliches and speak without saying anything.

The result is an announcement only an idiot could believe.
