If Joe Biden gave a speech and claimed that the Prime Minister of Hungary was "the leader of Turkey," we all know very well how Republicans would react.
"He has dementia!"
"He is unfit to serve!"
"He is an embarassment to America!"
But when Trump calls Hungary's Prime Minister Viktor Orbán the "leader of Turkey," Republicans don't bat an eye.
This is what hypocrisy looks like.
Personally, I don't think it's a big deal that he misidentified a foreign leader's country, but the outrage that the GOP would exhibit had Biden done this would have been ridiculous.
