The Clinton campaign should be both applauded and criticized. They came up with a brilliant strategy for handling Pence. But their strategy for handling their own candidate is awful.
To the first point, I gotta hand it to the Clinton campaign. They have studied their opponents and really figured out what makes them tick and how to get under their skin and rattle them.
First there was Clinton's expert troll job on Trump during the first debate. Everything from baiting him into insults, calling him Donald (which was visibly irking him) to calling the amount of money he has into question was designed to get under his skin and throw him off. Norice how Kaine has repeatedly challenged Pence to defend some of Trump's more outrageous, vitriolic, or down right stupid positions, saying things like "I can't believe Governor Pence would defend X." It instantly rattles Pence and causes him to stumble and dodge. It is the perfect strategy as Pence has already shown, virtually from day one on the campaign trail, that he is unwilling to either endorse or defend Donald's crazier antics. Kaine is putting him in a position where Pence either has to either defend it (at the expense of his credibility), break ranks and criticize Trump, or jump through hoops to dodge the question. It is clearly working and making Pence uncomfortable and forcing him to shift in ways he did not anticipate. He is quite unnerved.
However, Kaine is going too hard in the attack dog role. If the Clinton campaign wanted an attack dog, they ought to have picked Bernie Sanders, not Tim Kaine. This is not a role that fits him and he is clearly uncomfortable with it. They way he is constantly talking over Pence and the moderator is making him seem like a toned down version of Trump from last week. I don't understand why the campaign is utilizing him like this. Kaine's natural demeanor is one of cheerful optimism and a kind of "aw shucks" persona. It's served him well thus far and is, in fact, his biggest strength. Why backdown from it? Especially when debating Mike Pence who has a stuffy persona and seems to have a chronic case of stick up his ass.
Yeah, perfect strategy for handling Pence. Terrible strategy for handling Kaine. I think Kaine takes a bigger hit from it. Pence is rattled and unnerved but isn't having a breakdown (nor would he, this isn't a novice like Donald Trump). Meanwhile Kaine is coming off as an unlikeable big mouth and him constantly talking over the female moderator certainly doesn't gel with the campaign's attacks on Trump for mistreating and disrespecting women. Big takeaway: The Clinton campaign nailed the opposition research but dropped the ball on their own guy and that cost them the debate. Pence wins, IMO.
