I hate to say it, but I have a feeling that Dat is going to make it quite far- and potentially win. If they have the FINAL vote at 4, then depending on who the other 3 comics are, there's a good chance that those 3 comics will split the same vote, and Dat will win again with 30-something percent. That's what happened to him in season 1. He got like 35%, when really, 65% of the voters would have rather seen any of the other 4 comics win.
Hopefully they'll have the FINAL at 2, then there would be no way he would win.
Rich Vos- Probably not going to last too long. Might make it into the top 10 or so. If he and Dave are performing at the same time, he's screwed because Dave is pretty similar in style- but a lot better.
Tess- She'll be around for a bit, but not longer than Vos. But she could stay safe if she's gotta go into the head-to-heads with Rob, Tere, or Sean, but after that she's gone.
Geoff- I really liked the guy in season 1 and wished I had seen more of him. Probably will make the top 10, but won't get too far after that.
Rob- He's decent, but he's on his way out.
Sean- Never hated him like so many others seem to, but he doesnt have the star power to go far.
Tere- Never liked her style. She's out next week.
Dave & Ralphie- Arguably the best 2 comics from season 1, and I definitely see them making final 6.
Tammy & Ant & Kathleen- these 3 won't be lasting very long I don't think. Though I imagine Ant will last the longest of the 3.
Gary- Never liked him at all. My least favorite from season 2. Hopefully the viewing audience is getting tired of him by now.
Jay- He's growing on me, and he's got an enormous fan base. He'll make top 10, and probably top 8.
Todd- Man, I love this guy. He's my 2nd fav from LCS2, but mostly just his inhouse antics. He's not all that great on stage.
Alonzo and John- they're making the final 4. Definitely.
Corey- won't make the top 10 because women find him offensive. I'd love to see him in a sit com though! I think there's a good chance he might be the next to go.
So, here's how I see things shaking down
After that, its pretty tough to call. I'd like to think that Dat and Jay would be out, but you never know. If Dat makes final 4, the only comic who could potentially steal votes from him would be John.
