I'm expecting that too, and yeah, it's definitely for the best she doesn't go. I'll be shocked if she does somehow.
Ugh, Bernie is literally making me worry about my future here.
Dammnit man, get yourself together!! I'm diablosing!😞😠
Think of it this way. One of three things would be likely to happen: 1) Bernie tears Trump a new asshole [I think this is most likely given his ideological revulsion towards Trump and the Trumps of the world] 2) Trump tears Bernie a new asshole (possible, given the amount of material available, and Trump's willingness to fight) and 3) Both of them sort of muddle through.
In case 1, Trump looks bad and Bernie looks good, but it doesn't really matter because Bernie winning requires a miracle at this point.
In case 2, Trump has just savaged Bernie, Saint of Birdies, ensuring the cult of Bernie either stays home or works against him.
In case 3, nothing much happens, and nothing much changes.
Will they tee off on Clinton? Some, I'm sure. But it'll be the same stuff that already hasn't worked well, and it will give an insanely bad impression -- two old men spending their debate slagging off a woman candidate. It'll drive more women voters toward Hillary, including possibly some of the young ones she's lost to Sanders. Nothing either of them says is going to have a profound effect on the base, and the idea that Trump will somehow soften his positions enough to be acceptable to people who want to burn down Wall Street is just silly.
