Presidential race moves to 'Amtrak primaries'

Some pundits have dubbed it "Amtrak primary" day: All eyes will be looking East in the presidential race Tuesday as Connecticut, Delaware, Maryland, Pennsylvania and Rhode Island hold their primaries for both parties. (All states served, of course, by Amtrak.) Front-runners Hillary Clinton and Donald Trump are expecting wins in several states, especially Pennsylvania, which carries the day's biggest delegate haul. Trump's Republican rivals Ted Cruz and John Kasich are looking past the Northeast and have teamed up to stop Trump in Indiana on May 3 and in other states.
