Political vocabulary display

In a comment on "The most Trumpish (and Bushish) words", D.O. wrote "It seems that we are missing (at least I was missing) a key piece about Mr. Trump's and Mr. Bush's speaking style. Mr. Bush is using significantly more words than Mr. Trump". A traditional way to look things of this kind uses a plot of word type count against word token count. And a type-token plot suggests that Mr. Bush's rate of vocabulary display is indeed greater than Mr. Trumps's:

The specific recipe for this plot strung together the following texts:

Trump-

His announcement His side of a press conference held on 8/11/2015 His side of a press conference held on 9/3/2015 His remarks from the first Republican candidate debate

Bush-

His announcement His side of Face The Nation 5/31/2015 His side of an interview with Sean Hannity 6/16/2015 A speech he gave on 8/11/2015 His remarks from the first Republican candidate debate

One factor to consider is that Trump's "texts" are all extemporized, while two of Bush's texts (his announcement and the 8/11/2015 speech) were delivered from a written version. Still, I suspect that even if we limited considered to transcripts of extemporized speech, there would be a (smaller) difference of the cited kind.
