Post-Gazette.com – WESTERVILLE, Ohio — Facing a do-or-die election in his home state today, Gov. John Kasich rallied about 1,000 supporters Monday, while Donald Trump 170 miles away worked to slam the door on his chief Ohio rival. Mr. Kasich is banking on his home state coming through for him today in hopes of establishing himself as the Republican alternative not named Trump. “The country is watching,” he said at a high school in suburban Columbus. “We are the geographic center of gravity in every political election, and it’s happening now, and it will happen again when I come here so we can beat Hillary Clinton this fall. “The whole world will be watching us, frankly, holding their breath about what we are all about,” Mr. Kasich said.
