Rubio is either not very bright or not honest. Of course Trump knows there are not 60 votes for this. That’s why Trump is needling McConnell to go to a 51 vote system. The Democrats, in his place, would have done it instantly.
McConnell won’t, though. He loves thwarting Trump and then snarking about how hard it is to MAGA. The Trump voter army will have to handle this. McConnell is safe for now, but a number of others aren’t.
It is.the lack of honesty.
Remember, when he first ran for office there were all these threads here with his speeches (in Spanish) to La Raza and other groups promising amnesty posted on YouTube for all to see and here.
Then he would go give speeches to Florida Republicans promising to secure the border.
He had to be lying to one group or the other and when the gang of eight Bill came out it was clear which one he had lied to.
That he later joined with McCain and Graham in arming ISIS was perfectly in character.
