Wisconsin Governor Scott Walker has formally endorsed Ted Cruz one week before the state's critical primary. "I am proud to endorse Ted Cruz," Walker told radio host Charlie Sykes on Tuesday. "After a lot of thought, a lot of time, a lot of prayer about this, I just really decided that after all these years of the Obama-Clinton failures, that it's time that we elect a strong, new leader and I've chosen to endorse Ted Cruz to be the next president of the United States."
