One of the worst arguments floating around against impeaching the president is that it is somehow worse for Democrats than for him. The argument is a favorite of white nationalist and Fox News host Tucker Carlson, and he’s not alone. Trump campaign manager Brad Parscale has also made a version of this argument.
Fortunately, someone has already debunked this argument, and that person is Donald Trump. Watch Trump really lean in during a November 24, 2014, appearance on Fox & Friends, saying that Republicans should impeach then-President Barack Obama and claiming that once impeached, the president would be “a mess” and unable to focus on anything else.
The unquestionable highlight is this quote (though don't sleep on the Giuliani cameo): “Do you think Obama seriously wants to be impeached and go through what Bill Clinton did? He would be a mess. He would be thinking about nothing but. It would be a horror show for him. It would be an absolute embarrassment. It would go down on his record permanently.”
To be clear, however one views Trump's argument, it is separate and independent from any legal questions about impeachment or factual questions about what happened. Trump was talking in the context of Obama’s executive action on immigration -- one of many calls from the right to impeach Obama.
