I predicted this a while back. Rubio is gaining because the Bush/Pataki/Christie/Kasich people are all starting to coalesce behind him.
In the same way, Cruz is starting to pick up the Huckabee/Santorum/Jindal people, while he and Trump are splitting the Carson defectors.
Trump or Cruz works for me. Both PITAs to the GOPeeeeeeeeeee! I wanna see McCornhole cryin with the tan man ...
