I would agree that her campaign has been cleaner. Part of that is probably Sanders' insistence on not engaging in personal attacks and part of that is probably Clinton's (reasonable) expectation that Bernie isn't a threat like Obama was.
Maybe I'm mistaking the vitriol in poligaf with the vitriol on the campaign trails because I know the 2008 primaries were way more contentious. Not too late for things to get dicey in 2016 though.
It is definitely still early. The more vicious parts of the campaign didnt really start till after Iowa when Obama got his first win and then subsequently lost NH. It really didn't start taking off till the south carolina primaries when some of the open hostilities on Clintons side started showing when they felt shunned by the African American community and that attitude started leaking out. The big event though was Super Tuesday, when it became clear that the state demographics heading forward did not favor Hilary that is when the real nastiness started to come out.
To be honest given the current climate and Hilary dominance among minorities this time I don't expect her to get nasty especially since she has a much better campaign staff then last time, I also don't expect Bernie personally to get nasty even if trailing, not at Hilary specifically anyways, I see him getting more contentious with democratic party leads then Hilary specifically, and I also worry his campaign staffers may have other ideas what it means to fight as an underdog in this race which is another wildcard. To me I don't think his staff speaks very well or for Bernie at all, and some of his more rabid supporters have made things a bit more socially contentious in my opinion then they were in 2008 but even then I don't think anything that happens this cycle will ever look like they did in 2008 as far as open animosity, not just between candidates but between supporters as well. May not have seen it on GAF but I can tell you there were a LOT of disgruntled Hilary supporters that were long time democrats that felt she was getting unfairly demonized. In retrospect I can see why now looking back, but I was a huge Obama supporter that I saw the more negative angles on the other candidate then positive ones they shared.
Its just a part of the process which is why whoever wins the primary I am looking forward to supporting whoever makes it out, I think either Bernie or Hilary would be 1000% better then current crop of Republican candidates, especially those at the top.
