Super Tuesday has arrived. It’s one of the most important days of voting in primaries and caucuses in the the 2016 presidential campaign. Republicans and Democrats each go to the polls in 11 states. About a quarter of all delegates are at stake. The five Republican presidential candidates will compete in contests in Alabama, Alaska, Arkansas, Georgia, Massachusetts, Minnesota, Oklahoma, Tennessee, Texas, Virginia and Vermont. Democratic voters will decide between their two candidates in similar states, except Alaska, and also in Colorado and American Samoa. Recent polls show billionaire Donald Trump could win at least eight of the 11 states.
