Watch out John Boehner:
Why would the people of Kentucky want a rookie Senator-- they have Sen. Mitch @McConnellPress who may be next Speaker & bring $'s to KY?
— @realDonaldTrump
While it would be easy to assume that Trump is just a clueless buffoon who doesn't understand the difference between endorsing someone to be Senate Majority Leader and being Speaker of the House, there's an alternate explanation—given that you don't actually have to be a member of the House to be Speaker of the House, maybe he just got McConnell confused with Ted Cruz?
Update: Democratic nominee Alison Lundergan Grimes has some fun with Trump's Twitter misfire:
Thank you @realdonaldtrump for firing @Team_Mitch and running him for "Speaker." Kentucky needs a new Senator. #kysen
