Good points.
Another thing that must be remembered about LBJ is that he only served six years. And in those six years he accomplished, to our detriment, more than most presidents do in eight years.
Imagine if you will, if Johnson had served a total of 10 years.
With his super majority and milking the memory of a man he had assassinated? The mind boggles.
Though without McGovern (only possible because LBJ didn’t run) the looney Left in the RNC at the time wouldn’t have bolted for the DNC and it is likely we’d have far worse than RINOs today in the RNC (for example: Hillary might still register Republican).
Imagine if Kennedy had served his term and projected 2nd term? He was just as bad as Johnson. He just didn’t get the chance to prove it.
