(Edited-in note: I want to see Kord, Moradin, Nerull, or Obad Hai as last Power standing. Preferably Kord or Nerull.)
I'm just voting for the ones I hate most, like least, or just find overly redundant. Wee Jas has a silly name, but so does Boccob, and at least she's an interesting deity (though should've stayed a demi-deity maybe), so I'll be voting Boccob off sooner or later.
Fharlanghn is tough to spell or pronounce correctly, and a stupid name, plus he's boring as heck. One meager, extremely limited portfolio element? No real hooks or interesting facts? The core pantheon could do a lot better for a patron of Travel.
Ehlonna, Pelor, and St. Cuthbert I find kinda redundant, with the other deities that fill their most basic alignment/portfolio niches. Obad Hai is a better nature deity than the other two, and could be taken in interesting directions I think. Ehlonna's confused and limited in scope, rather than being interesting. Pelor is dull and overly broad on the other hand, kinda redundant too. St. Cuthbert just doesn't make a lot of sense at present, and should probably still be a demi-deity or quasi-deity, plus he steps on the toes of Heirroneous and Hextor, rather than representing different aspects of Lawful alignment that aren't already covered by core deities.
Gruumsh is rather limited, and I don't think he would really support non-orc followers, so he might get my vote eventually for being too limited for the core pantheon. Although I don't particularly like Hextor or Erythnul, they're at least more fitting. Though, if Erythnul gets the bag, there'd need to be a different Chaotic Evil deity.

And both Erythnul and Kord need to be fused into a CN god of Barbaricness. You know, the one that drinks with Olidammara, chases Eilistraee and Sune's skirts, and beats the snot out of either Hextor or Heironeous depending on who is more sanctimonious that day. So everyone, welcome Korythnul!
I must second Felix's notion. Korythnul, God of Barbarism, demands it!
