After the first failed vote, go talk to Murray.

He says he'd only vote for you if he knew you would be tortured for it
Have you spoken to Noogie about the Brotherhood yet? He will give you the induction manual for new members of DUBMI.
Show the manual to Murray....
Oh well, it's not really torturous enough. Take a look at the manual.
Hmm... the cover is loose. In games like this, it means you can probably swap the book cover with another book.
So maybe finding a book on torture... where could that be?
Hey, wasn't there a torture device down there somewhere? The Iron Monkey?
Hmm... can't get there, the pipe is blocked. Need something caustic to clear it out...
What's the most caustic substance we can find nearbile, er nearby?
Get some more yellow bile in your mug, and use it on the clogged protuberance
Use the unclogged protuberance to get to the Iron Monkey, and open it
Oh cool, a torture manual!
Now you know what to do to get Murray's vote
