WASHINGTON (AP) — Donald Trump scored a five-state East Coast sweep Tuesday to embolden his hopes of clinching the Republican presidential nomination without a catfight at the convention. Democrat Hillary Clinton, on the cusp of closing down Bernie Sanders' remaining presidential hopes, advanced toward that goal with wins in Maryland, Delaware, Pennsylvania and Connecticut. Loretta Becker, a pharmaceutical sales representative, explaining how the desire to stop Trump motivated her to vote for Clinton in Warwick, Rhode Island. Another motivation: "I really loved having Obama for president and now having Hillary as a president, feeling like she'll do a great job and knowing that she's the best candidate and wanting to vote for her and support her." Most of the GOP delegates — 54 — are being directly elected by voters, with their names listed on the ballot but no information about which candidate they support and no obligation for them to have to line up with one of them. [...] Trump has a distinct path to winning the nomination before July but little room for error. Rep.
