Looks like Rubio is getting his endorsement bump.
Latest biggies — Tim Scott, Rick Santorum and Pat Toomey.
Here’s a list now:
U.S. Governors (former)
Robert List, Nevada (former)
George Pataki, New York (former); 2016 presidential candidate
George Allen, Virginia (former Virginia Governor and Senator)
Scott McCallum, Wisconsin (former)
U.S. Senators (current and former)
Arizona: Jon Kyl (former)[
Arkansas: Tim Hutchinson (former)
Colorado: Cory Gardner
Idaho: Jim Risch
Montana: Steve Daines
Oklahoma: Jim Inhofe
Pennsylvania: Pat Toomey, Rick Santorum (former) (also former 2016 presidential candidate)

I would think Kay B. Hutchison will be on board soon too.
