I support Cruz. However, national polling is irrelevant. How the candidates poll in the early primary states is a better indicator of their chances. By that measure the averages at RCP show:
Iowa: Walker has a firm lead.
New Hampshire: Walker leading.
South Carolina: Bush and Walker essentially tied.
Florida, no averages at RCP yet: My guess is that either Rubio or Bush would be leading there.
Few considerations:
1. Both Bush and Walker haven’t formally announced so their true support hasn’t been fully revealed.
2. Walker might have more fragile support given he still is a relative unknown to most Americans.
Another supposition: Walker or Cruz, but not Bush, might feel inclined to fit Rubio into the VP slot in order to better their odds in Florida and with the Spanish speakers.

Walker or Cruz would diminish their chances in the general by adding the cheap labor importer Rubio to the ticket.
