Has Trump Met His Match in Rubio?

After training his fire for much of the summer on former Gov. Jeb Bush, Donald Trump has found a new favorite Republican rival to taunt: Sen. Marco Rubio, the New York Times reports.

“But Mr. Rubio is proving capable of giving it back. And Mr. Trump also discovered on Friday that some conservatives do not respond as kindly when the insults are directed toward Mr. Rubio, who is not viewed with the sort of suspicion that Mr. Bush engenders among hard-line activists.”
