Mitt Romney took an important step towards the GOP nomination this week by sweeping primaries in Wisconsin, Maryland and the District of Columbia. But Rick Santorum says only half of the delegates have been determined and he intends to keep his campaign going all the way to the convention. John Gizzi of Human Events says he takes Santorum at his word but still believes Romney will wrap up the 1,144 delegates he needs before the convention. He explains how Romney can do that and why Santorum and Newt Gingrich will stay in the race even though they know the odds are stacked against them. Gizzi also weighs in President Obama’s strong comments about the Supreme Court, his harsh criticisms of Paul Ryan’s GOP budget and the rocket launched into Israel from Egypt.
