I personally don't see the major appeal for Charleine that everyone else sees. Her PMing this week was utterly abysmal and had she not made that saving sale (which seemed like pure fluke more than anything) would have seen her fired.
Completely sidelining an entire team member just because you think he's a bit of a prick isn't the way to go and the bloke can sell, sure you can point out how he had a rough pitch a few tasks back but I get the feeling that could well have been an "off day" and even if it wasn't, it still would have been an improvement over Charleine's pitch that just seemed stilted, and laden with hesitation and word-fumbling.
Basically what I'm saying is I prefer Richard to Charleiene. And as for the actual title of this thread, no, Richard isn't even close to the most unlikeable candidate ever.
Melissa from S6, Saira from S1, any of the candidates from S4 (excluding Lucinda), Adam from S8, Katie Hopkins and of course Selina from this year are all much more detestable than Richard, imo of course.
