Early at Wednesday night's Republican primary debate, it was unclear which Donald Trump was standing on stage.
Was it the Donald Trump who admitted just before the debate that he could afford to "tone it down a little bit."
Was he the kind of guy who in his 30-second opening said he doesn't want to be "braggadocious," but shortly thereafter talked about making "billions and billions of dollars." (Yes, that sentence counts as toned-down for Donald Trump).
Or was it the bombastic Donald Trump we've all come to know -- the kind of guy who can't resist cheap but clever and stinging jabs at his opponents?
Shortly, it became clear which Donald Trump was standing on stage. It was the Donald Trump who can't resist saying things like this:

In the evening's undercard debate featuring the bottom four candidates, former New York governor George Pataki said Trump is "unfit" to be president, adding:
Once the main debate got started, Trump couldn't resist hitting back on Pataki, who we'll point out is registering near the bottom of the polls and wasn't even on stage when Trump said:
And then we were on to Carly Fiorina. Trump, of course, ruminated about the former Hewlett-Packard CEO's looks to Rolling Stone magazine in a recent interview: "Look at that face! Would anyone vote for that?" (He later said he was speaking about Fiorina's "persona.")
No surprise, CNN moderator Jake Tapper asked Fiorina, the only woman in the Republican race, to respond on Wednesday night.
"I think women all over this country heard very clearly what Mr. Trump said," she coolly replied, halting her answer for emphasis.
