Let the voting begin. Polls have opened for Super Tuesday. Voters in Arlington, Virginia showed up as soon doors opened at 6 to cast their ballot. With 11 states voting, more delegates are up for grabs today than any other day in the presidential nominating contest. Front-runners Hillary Clinton and Donald Trump are poised for big wins. Polls show Trump leading in nearly all the Super Tuesday states putting him in position to seal the nomination against his opponents. Clinton has a big lead in six Southern states that have large blocs of black voters, who have been slow to warm to Bernie Sanders.
