The Republican party has transformed into the Trump Maga party | Sidney Blumenthal

When Richard Nixon's perfidy was exposed, his party support crumbled. But with Trump, GOP leaders rallied around him

The Republican leaders were of one mind: if the Republican president committed a crime, he could no longer hold office. They had defended him to a point, but they understood that with proof of criminality they would withdraw their support. Even before the evidence was conclusive, their ultimate judgment about their constitutional duty and of the president's was certain. If it can be proved that he lied, resignation would have to be considered. It would be quick. Everything would be over, ended. It wouldn't drag out like impeachment." So stated senator Barry Goldwater, a previous Republican presidential nominee, still the icon of the conservative movement, in May 1973.

It did not matter that Richard Nixon was popular, that he had won the presidency twice, the last time just a year earlier, in a landslide, carrying 49 states. Goldwater did not know that after he made his statement, the smoking gun" tape would be revealed on 5 August 1974. He and the other Republican leaders, however, did know then that a president who had authorized payment of hush money to the Watergate burglars in order win an election and had engaged in a coverup to thwart both the investigation and accountability in the courts would have to quit or face impeachment and removal.
