One thing he couldn’t do is keep Cruz from committing political harakiri.
This seems to be a virtually impossible act for Trump.
It was really odd. He he pumped $10M into Cruz’s “Keep the Promise” PAC which was run by Kellyanne Conway, who is now working for Trump. And even with his equity in Brietbard, the Cruzbots constantly complained that Brietbart was “pro-Trump”. It would be interesting to know more about what makes Mr. Mercer tick.
