Donald Trump is undermining his own cause with tweets, such as his latest one aimed at CNN, which are simply un-presidential, holds Jonah Goldberg of National Review. His inflammatory rhetoric on Twitter has needlessly entrenched Democrats in their stance against him. Moderates also have been scared off by comments seen as somewhat rough and antagonizing. Trump’s use of social media may have been beneficial during his electoral campaign but he needs to change his tactics as the president of every American, not just his supporters. His provocative tweets unnecessarily continue to divide the country even further, and are proof that he should walk away from Twitter.
