Cruz is going to be President in 2017, I think he has already selected his VP and his entire cabinet and his administration will be the power house needed to restore, protect, defend and promote world wide our Constitutional Free Republic.
Right now their is a wall between America and Washington a strong wall built by the Progressive Liberal Democrat/Rino Communist Party, Cruz will proclaim to these enemies of our Republic...Tear Down This Wall... and then proceed to be the wrecking ball not waiting for a response.
Cruz/West 2016
The problem with naming a VP now is that he'd be tying himself to that person. If they blunder, it might damage him too. Why risk it?
Ted Cruz has the ability to win without having to either join with, or even attack, the others. Of all of them-He makes the best, most compelling case for conservatism.
