Wisconsin’s Walker exits ’16 race with harsh words for Trump

MADISON, Wis. (AP) — Warning that the Republican presidential race has become too nasty, Scott Walker exited the 2016 campaign on Monday and urged others to quit, too, and "clear the field" so someone can emerge to take down front-runner Donald Trump.
The announcement marked a dramatic fall for Walker, who was struggling to generate money and enthusiasm after surging into the race's top tier earlier in the year. He will return to his job as governor of Wisconsin, where his term runs through 2018.
