Ron DeSantis gripped a baseball, looked at his 5-year-old son, Mason, and lobbed him pitch after pitch. He grinned at Mason's hits and rolled his eyes when his own pitches came in too low or too high. “Bad pitch, buddy,” the Florida governor said after one errant throw. “That one was my fault.” DeSantis, who battles a reputation for being stiff and unfriendly, approached the field wearing a fleece campaign vest and long-sleeved shirt with his sleeves rolled up. The heat was starting to ease with sunset.
