I still think Katie Hopkins was awesome. If you ignore her pantomime-villain asides I reckon she was easily the most intelligent and capable candidate of S3.
Tre was just a bully - but being a bully is OK as long as you're funny with it.

He was a complete loose cannon and only occasionally made a good point - the rest of the time he was just shouting for people to shut the f*ck up and calling them all kinds of nasty names. I also remember him being less than impressive as a PM. He won the first time because the other team messed up massively (I think that was the Selling Kisses debacle), and the second time it completely fell to pieces. Terribly overrated as a businessman and as entertainment.
Kristina also reminded me that she was actually quite awful as a person, and I think if Katie hadn't been there she would have taken the role as Series B*tch. Definitely more deserving than Simon - but like she says, Sir Alan picks people based on whether they would "fit in", not whether they're the best.
Saira reminded me of how awesome she was in S1. lol @ the megaphone. She looks fab now!
