Carl Bernstein, the legendary journalist who helped uncover the Watergate scandal, recently said the real “heroes” who brought about the end of the Richard Nixon presidency were Republicans who told the president that his impeachment in the House of Representatives was a certainty.

And so was his conviction in a Senate trial.

Sen. Barry Goldwater led a GOP team of lawmakers to the White House to tell the president his Senate support had all but vanished and that Goldwater was not among those who would vote to acquit him.

Nixon resigned on Aug. 9. 1974.

I mention this because there appears to be no sign of any Republican “heroism” developing as the walls close in around Donald J. Trump, the current Republican who happens to be president of the United States. The GOP is holding firm in both the House and the Senate — with a few exception — in its support of Trump against the special counsel’s examination into what I like calling “The Russia Thing.”

Might there be some heroes emerge if the counsel, Robert Mueller, produces incontrovertible proof of, say, obstruction of justice, or of conspiracy to collude with Russians who attacked our electoral system, or of violations of the Emoluments Clause in the Constitution that bans presidents from accepting gifts from foreign kings and potentates?

I cannot predict the future any more than meteorologists can predict with absolute clarity what the weather will do the next day.

Why the absence of any GOP heroes? President Nixon never grabbed the party by the throat in the early 1970s. Sure, he won re-election in 1972 in a historic landslide. However, the party didn’t exactly belong to him. Fast-forward to the present day and we find that Donald Trump has managed — through an astonishing display of intimidation and innuendo — to capture the heart and soul of a party with which he had only a passing acquaintance prior to becoming a politician, which was when he announced his presidential candidacy.

Because I don’t predict these matters any longer, I am left just to wonder whether there might be a hero or three out there among the Republicans who serve in Congress. What might it take to shake them loose from the death grip that Donald Trump has on them?
