Do you think President Trump's penchant for Twitter diatribes is doing more harm than good? You're not alone... in fact, you might be in the majority. ABC News and the Washington Post have conducted a national poll suggesting that 67 of Americans disapprove of Trump's use of Twitter. They're more likely to use negative descriptions of his behavior, such as "dangerous," "insulting," and "inappropriate," and unlikely to use positives like "interesting," "effective" and "refreshing." And no, this isn't as skewed by political leanings as you might think: only 41 percent of Republican supporters believe the tweets are refreshing, for instance.
