At the same time, by historical standards it was a narrow victory for a would-be presidential candidate. No sitting senator or governor in modern times has parlayed a home-state election that close and competitive into a presidential nomination. Few have even tried. Kasich won his 2014 race by 31 points, Cruz won his 2012 race by 16 points, Rubio won his 2010 race by 19 points and Paul won his 2010 race by 12 points.
