If anyone thought Marco Rubio was going to train all his fire on Ted Cruz at Thursday night's debate rather than Donald Trump, the Florida senator disabused everyone of that notion quickly.

It started with a spirited exchange with Trump on immigration, where Cruz entered the fray, too.

Soon after, Rubio laid into Trump over his business records. He said he was successful only because of an inheritance, hit him on bankruptcies, you name it.

The exchange, in which both talked over one another, culminated with Rubio saying to Trump that he would be "selling watches in Manhattan" if not for his family fortune.

The Rubio campaign clearly wanted to highlight the moment, advertising on its website a $10 "Trump Watch" with a shattered face.
