The decision by the donor, Paul Singer, a billionaire New York investor, is a signal victory for Mr. Rubio in his battle with his rival Jeb Bush for the affections of major Republican patrons and the party's business wing.

Guess Singer has plenty of money, thereby plenty of clout. I hear also that he has been making calls and contact with Bush donors to come on over— to Rubio.

In the end, I actually don’t believe Bush will go after Rubio all that hard. For one thing it’s futile, and as Trump has said, Bush is probably too “low energy” to pull off much of a hit job. LOL!!
