 He wasn't getting out by choice. It was as much a voluntary departure from the race as all those people accidentally falling out of windows in Russia. He felt pushed out. Party leaders were badgering him to get out. A growing number of members of Congress were telling him to get out. Donors were telling him to get out. There were only about five people left telling him to stay in. And he felt like he had to do it because everyone wanted him to do it, even though he himself really thinks he can beat Trump.
