"This comes at a time when Trump’s approval ratings are at an all-time low, just 6 months after taking office. A Washington Post/ABC poll released Sunday put Trump’s approval rating at 36%, down 6 points from April. A Bloomberg poll from Monday, meanwhile, puts him at 40%. These results also mirror Nixon’s own ratings at the same point in his presidency — 39% approval, 49% disapproval. 1973 was a critical year for Watergate. It is the year Senate hearings were televised, a special prosecutor was appointed (and later fired in the “Saturday Night Massacre” which additionally led to resignations of the Attorney General and Deputy Attorney General), and Nixon declared that he was “not a crook.” All the while, his approval ratings did not reach the level of Trump’s current ratings until after the “Watergate Seven” were indicted, 4 months before Nixon resigned on August 9, 1974. Trump has one advantage that Nixon did not: a shield of Republican lawmakers in Congress."
