The GOP tries for the moderates and independents on both sides, and would love to get the far left, and despise the right
Cruz appeals to the right, will appeal to anyone with a brain that works. That leaves out the libs. He can get all the moderates and even the far left who think more tha reactionary libs
Watch out
How soon they forget that SC went for Newt Gingrich. They will go with Cruz IF he runs
