I guess the good thing is, DI isn't
always right (although it's been fairly accurate this season).
Of course last week it couldn't have picked a worse time to be wrong 
I do think Ralph's time is up. I was surprised he lasted this long, and figured he'd make it to the final 4 at best. However, I wondered if maybe his fan base was bigger than I originally thought, or if he saw a surge in votes. If Chelsea/Mark aren't bringing in the votes, and it surprises TPTB, maybe they should try and understand why that is. Mark's been a disrespectful douche this season. He screwed Chelsea over. I don't know that I'm all that crazy about her, but there've been times I've pitied her. If they want ratings, send Mark home, or out in third, and watch his tantrum/trash talk show guest-style rampage. That'll get them ratings

It's not like they're protecting his reputation by manipulating the show to keep him in. Everyone except his fans think he's a tool, a spazz, and a spoiled brat with an ego that makes me wonder how he can even fit in the ballroom anymore.
If it is true that Chelsea/Mark are in a distant third, despite trying to give them a huge advantage-way to go producers

That worked well. And you've ticked even more viewers off in the process. Here's hoping they don't try and manipulate the scores next week to earn Mark his precious little mirrorball. If he and Derek aren't friends anymore, who cares if they match? Maybe that's why he's taking it so personal this season.
