Plus he’s taking about $170,000 a year to be a Senator and doesn’t show up much and he said he hates the Senate and that’s why he’s missing votes as he doesn’t like to be there. He should resign and definitely shouldn’t be president.
I think Rubio has already said he’s not going to run for reelection to the Senate.
Like Carson and probably some others running, he’s just trying to amass personal campaign money that he can keep when he drops out.
