Rubio is going to be the GOPe stooge of choice, it’s just a matter of by how much at this point, which will probably affect who does or doesn’t drop out in the establishment lane. I think anyone who comes in at over 10% today will stay in until 3/1, personally.
Endorsed by (governor Nikki Haley + Trey Gowdy + sen Tim Scott) has to have some effect on Rubio.
