WASHINGTON — Former reality TV star Donald Trump tweeted Tuesday that the problem with the Oscars is “we don’t have Stars anymore” — except for him. Just kidding, the president hastened to add. Viewership of Sunday’s Academy Awards broadcast plunged to a record-low viewership of 26.5 million people. According to the Nielsen company, that’s a 20 percent drop from the 33 million people who watched last year’s show. Lowest rated Oscars in HISTORY.
