The nation’s political punditry is telling us about all that “energy” that emanates from Sen. Bernie Sanders’ rallies.

The independent senator’s supporters are all in with Bernie. You can feel it, man! They’re going to carry the 78-year-old democratic socialist to victory against Donald John Trump in the fall, presuming of course that he gets the Democratic Party presidential nomination.

But … will he? Does that energy translate to votes?

I was part of an earlier “revolution” back in 1972. We thought we had “energy,” too, as we backed the candidacy of the late Sen. George McGovern.

I had returned home from the Army in 1970 after serving for a time in Vietnam. I was all in on McGovern’s stated intention to end the war. I enrolled in college. I became a political activist. I registered voters at the campus where I attended classes. We signed up a lot of new Democrats.

We went to rallies. We cheered loudly. We filled a downtown Portland, Ore., square when Sen. McGovern came to exhort the thousands of followers.

Hey, we had “energy.” We wanted to kick butt … by golly.

Then came the election. The networks called it almost immediately after the first polling stations closed on the East Coast.

It was over.

We were crushed under the weight of a 49-state landslide.

Don’t misunderstand me here. I want there to be enough energy to carry over that defeats Donald Trump this fall. I don’t know if Bernie Sanders is the guy to ignite the flame.

I just remain dubious of the pundit class’ penchant for hailing all the energy it feels from these Bernie Sanders rallies.
