Trump Sweeps Five States, Clinton Wins Four

Donald Trump is declaring himself the "presumptive nominee" after a clean sweep in five primary states. Political expert Dr. Sean Foreman of Barry University says he now has a legitimate claim to that title. Trump notched wins in the GOP primaries in Pennsylvania, Maryland, Connecticut, Delaware and Rhode Island. With this series of decisive victories, Dr. Foreman says it's hard to see how Trump is denied the nomination, even if he doesn't earn enough delegates to secure the nod before the convention. Trump's rivals Ted Cruz and John Kasich have a tough road ahead of them. Dr. Foreman says next week's contest in Indiana will be Cruz's last chance to recover from this recent spate of losses.

On the Democratic side, Hillary Clinton increased her lead over Bernie Sanders with wins in Pennsylvania, Maryland, Connecticut and Delaware. The only race she didn't win was Rhode Island, which went for Sanders. Dr. Foreman says Clinton needs to now unify the Democratic party and find a way to bring Sanders' supporters into her camp.
