Young supporters of Republican Donald Trump or Democrat Hillary Clinton agree improving the economy is a major issue. But young supporters of the two main presidential candidates disagree about the remaining top issues. That is what a new poll by the John F. Kennedy School of Government at Harvard University found. The poll suggested young Americans supporting Trump consider the spread of terrorism and dealing with immigration as two of the main issues. Supporters of Clinton consider reducing inequality and uniting the country as two of their top issues. Harvard released the poll Monday to mark the start of the Republican National Convention in Cleveland, Ohio. On Thursday, Trump, a wealthy businessman, is expected to accept the Republican nomination for president. Democrats are expected to nominate Clinton, the former secretary of state, next week at their convention in Philadelphia, Pennsylvania.
