Absolutely! With the general American Public, it seems that you can dress up anything with flowery words and speech, and they will go for it. Only the "elite" know when a politician is full of bs. I'd say about 65% of the general population just thinks, "Oo! She used a big word in a sentence, she must be smart."
For the rest of us, the content of the speech does matter. And too many flowery words just makes the candidate look like the speech was written for them.
