Rand will brutalize him in the debates.
Rubio *sponsored* SOPA/PIPA. EVERYBODY remembers the Wikipedia blackout. As soon as that happened Rubio pulled support from his own bill.
He voted YES to NDAA if I recall, as well as other civil-liberty infringing things.
And there was, way early in his Senate term, some fast-track bill that would've made Georgia (the country) a member of NATO, while Russia was invading them. That would have meant that we (as a member of NATO) could have immediately been dragged into a war with Russia.
I single senator blocked that bill from being fast-tracked: Rand.
