What speech does Armpit deliver using Coo as a prop, and how does Tatiana respond?

Armpit nervously gives his speech, sticking to his intended plan even though some of his classmates laugh at what he says. He comments that Ginny is the bravest and strongest person he knows, and if the strength and support of Coo can do that for her, who knows what he could do for the world. That, he says, is why Coo should be elected. After class, Tatiana tells him she liked his speech, even though he was nervous, and says she's going to vote for Coo.
