Even as his campaign struggles for survival, Sen. Ted Cruz dominated weekend delegate selection contests that he and other Republicans hope could block Donald Trump from winning the party’s nomination at their national convention. From Virginia to Arizona, the Texan nearly ran the tables at state party conventions where delegates were picked to attend the July meeting in Cleveland. Trump has won the most state primaries, including a sweep of five Northeastern states on April 26, and has gained over 10 million votes from primary and caucus voters so far, to Cruz’s 6.9 million.
