NEW YORK: Donald Trump has dominated the Twitter battle for the White House by insulting and belittling his rivals, but he has found a formidable social media opponent in the fiery senator and potential Democratic vice presidential pick Elizabeth Warren. While Hillary Clinton prefers to ignore the attacks of her Republican adversary Trump, who blasts the former secretary of state as “crooked,” Warren has no qualms about wading into the fray. The first-term lawmaker from Massachusetts and former Harvard law professor has successfully harnessed social media, in particular Twitter, as a medium for punching out at The Donald. In her anti-Trump Twitter storm she denounced the candidate as one who “incites supporters to violence, praises Putin,” says he is “cool with being called an authoritarian,” and “puts our servicemembers at risk by cheerleading illegal torture.” Warren is a liberal Democrat with a passionate following. Many supporters have urged her since 2014 to run for president, although she declined to enter this year’s contest.
