There are two tactical approaches for candidates seeking their party's nomination in election campaigns. One is to strongly debate the issues and firmly advocate your positions, but to avoid personal attacks on your opponents or needless divisiveness. The other is to vigorously attack your fellow candidates, disparaging them personally and seeking to raise yourself up by dragging them down. Ronald Reagan was famous for epitomizing the former path. Donald Trump, unfortunately, has chosen to follow the latter course... At a time when the nation is suffering under one of the most divisive and incompetent presidents in history, our people need positive, unifying leadership, not negative, destructive political rhetoric.
