Donald Trump's terrible, horrible, no good, very bad week
This was Donald Trump's worst week of his campaign since he lost Iowa to Ted Cruz exactly two months ago. To recap: On Tuesday, his campaign manager was charged with misdemeanor battery. Also on Tuesday, he backed away from his pledge to support the whomever becomes the GOP nominee, giving his Republican critics extra ammunition against him. On Wednesday, he suggested on MSNBC that he would advocate punishing women who seek an abortion, angering both abortion-rights supporters and opponents. (He later backtracked from that abortion statement.) And on top of it all, he finds himself trailing in Wisconsin, which holds its primary on Tuesday. Make no mistake: After Wisconsin, the primary calendar looks much more favorable for Trump, with the map turning to New York (April 19), Connecticut (April 26), Delaware (April 26), Maryland (April 26), Pennsylvania (April 26), and Rhode Island (April 26). But there's a reason why Trump was meeting with Republican National Committee officials in Washington yesterday -- he's got to start getting a better handle on the delegate rules, especially if the nomination is going to come down to a handful of delegates.
