No question, Rubio is weak on amnesty to illegals based on his gang of 8 history. However I would much rather see Rubio campaigning for Trump rather than Kasich or Bush. 2 old white guys on ticket will be exploited by MSM. Rubio is more gifted politician than Bush & Kasich. And he could get some Hispanics to vote for the ticket.
As VP, he can not force amnesty on Trump, even if he wanted to. And he is a good contrast of youth with Trump approaching age 70 this year. Last but not least, Florida is more critical than Ohio.
No to a Trump-Rubio ticket!
