If Emily is not F1, she will be the Bachelorette, for sure if she wants to and I think she will. After all, she has a daughter to support and the $$ she would make for doing it would be welcome when you have to raise and educate a child and alone at that. However, I'm sure the Hendrick's family help her in supporting their grand daughter.
If for some reason, Emily is F1, I would like to see Ashley H or Shawntel. I just cannot warm up to Chantal in a grand way. Having said that, Chantal has literally narrated this entire season, just like Chis L did during Ali's, and he was F2 and they beeeegggged him to be the Bachelor and as we know, he refused. If Chantal ends up F2, I'm pretty sure they would ask her first, even though I hope not. I think she is too busty to be the lead and she doesn't have that great of a figure, just like Ali didn't when she did the show.JMO When you look at Chantal, you don't look at her face first! If the rumors are true about the cheating, she definitely will not be it, or I hope not.
As far as the gals from Jake's season, Gia & Vienna, they can hang it up & move on, because their 15 minutes are over. Brad has too many great girls on his season for them to have to consider anybody else.
