Cruz Is Out as the Trump Train Rolls On

“This cake is baked.” That’s how one consultant summed up the prospects of Donald Trump securing the GOP nomination, and that was before Ted Cruz had officially dropped out. Though John Kasich vowed to fight on, party chairman Reince Priebus declared Trump the “presumptive nominee.” Can the GOP unite behind a man who tried to tie Cruz’s father to the JFK assassination?

Sanders Digs Deep for a Victory

Much like the Energizer Bunny, Bernie Sanders just keeps going and going and going. His victory in Indiana over Hillary Clinton is keeping his agenda front and center as she tries to sew up the Democratic nomination. Given the way delegates are doled out, Sanders would need overwhelming victories in the remaining primaries to overtake Clinton. But don’t tell those odds to his supporters.
