Donald Trump tweeted Saturday that Sen. Mitt Romney could have beaten Barack Obama in 2012 if he fought the former president as much as the current president.

And once again, Trump is acting like a child.

“If Mitt Romney spent the same energy fighting Barack Obama as he does fighting Donald Trump, he could have won the race,” Trump wrote on Twitter, adding “(maybe)!”

He shared a clip of Romney appearing to be emotional as he lost the election in 2012.

Trump was responding to Romney’s assertion on Twitter that he was “sickened” by the revelations in the Mueller report of the “dishonesty and misdirection” by the president.

“That was a race, folks, that should have been won,” Trump says in the clip about 2012.

Trump has a history of mocking Romney as a candidate who “choked like a dog” in the 2012 election, even saying that the former Massachusetts governor “walks like a penguin.”

“Once a choker, always a choker,” he said.

Twitter had some thoughts:

Obama > Romney > Satan > Trump

@MittRomney is right but doesnt go far enough. You belong on trial for obstruction of justice the same way any other citizen would be. You tried at least ten different times to obstruct an investigation to save your own skin. https://t.co/DpFEegY5Di
