Refudiate, Propulgate, Malaprop, Portmanteau, Art, Life

I realize I make this connection very, very late in the game, but it occurred to me this afternoon just how uncanny it is that Aaron Sorkin*, in The West Wing, prefigured Vice Presidential candidate Sarah Palin's portmanteau malaprop "refudiate".
In the episode titled "Disaster Relief", fictional Vice President "Bingo Bob" Russell uses the word "propulgate" at a conference at the White House in the Roosevelt Room.

Gary Cole as VP Bob Russell in The West Wing

From the West Wing script:

VP Russell (played by Gary Cole): Excuse me, Toby, if I may. You're right, Congressman. If we lower cap gains taxes, we reward the small business owners who took a risk for the economy and I'd be the first in line to pat 'em on the back, but the thing is, the Speaker is trying to "propulgate" a tax bill onto an appropriations package. We start allowing that, we're never going to get budgets passed.
[Leo, Toby, and Will look confused at the VP's word choice.

LEO [con.] (played by John Spencer): ... although I'm pretty sure there's no such word as "propulgate". Maybe he meant "propagate", or "promulgate".

--The West Wing, from the episode titled Disaster Relief

The fact that the two neologisms rhyme is icing on the cake.

*Credit for the prophetic malaprop perhaps should go to Alexa Junge, author of the teleplay.
