It’s good to hear that you have your finger on the pulse of the Trump-supporting public. If you could, please explain to everyone why you think people support Trump. Please do so without any anger, insults, or belittling. Thank you. :-)

He is the thinnest kind of an impostor--has come here with a lot of empty names and facts which he picked up somewheres, and you take them for proofs, and are helped to fool yourselves by these foolish friends here, who ought to know better. Mary Jane Wilks, you know me for your friend, and for your unselfish friend, too. Now listen to me; turn this pitiful rascal out--"
