Bombastic real estate developer Donald Trump announced his entry into the 2016 GOP presidential field today in a rally held at his self-named Trump Towers. Trump’s announcement may cause Daily Show host Jon Stewart to postpone his retirement after previously stating he would consider sticking around if “F*ckface von Clownstick,” as he calls Trump, jumped in.

Using Neil Young’s Rockin’ In The Free World — a song critical of the conservative policies of Ronald Reagan and George H.W. Bush — as his campaign theme, Trump made his announcement to a crowd that his own press office described as being in “the thousands.”

As might be expected, Twitter was aflutter with commentary from liberals and conservatives alike about the notoriously self-promoting businessman — mocking his speech, his reliance on talking about his wealth, and, of course, his hair.

Enjoy a sampling below:

“Trump: I’ll Be ‘The Greatest Jobs President That God Ever Created’.” I didn’t create you douchebag.

Now that Trump has given the ’16 GOP field its Rip Taylor, we can get back to the business of destroying Chairwoman Mao Tse Hillary.

Trump isn’t really a more ridiculous person than Newt Gingrich, and Newt Gingrich won the South Carolina primary calling for a moon base.

Trump using “stupid” a lot in speech. Know what’s stupid? Using “Rockin’ in the Free World” as your anthem and not knowing what it’s about.

The real challenge for Trump is going to be whether he can break out of this very nuanced wonk talk and throw some punches, make headlines.

Trump once sued a guy for libel for saying he’s less rich than he claims, and lost bc it’s true. Who says you can’t sum a guy up in a tweet.
