Umm there's no reason BB would want Sallie to leave. It was vote to evict. People don't care about spending their money on votes for someone that don't really dislike.
Lots of people disliked that Sallie was a bitch. She got a ton of votes.
Less people disliked Gina cause she's a spoiled brat. She didn't get as many.
Dexter didn't come off as bad as either of them. Less people are going to waste money voting for him.

You could say BB made it vote to evict just to get rid of Sallie.... but I highly doubt it.
