Bull-Pucky. The writer implies that significant percentages on "both sides" won't accept the results of the election if their candidate doesn't win. He makes a weaselly attempt to tell us there are slightly more Trump than Clinton people but his main point is both sides have this problem. 

When the chips were down, did the left throw a hissy fit and refuse to acknowledge GW Bush after his posse arguably rigged the Florida recount? H*ell no they didn't. Now before even a single vote has been cast Trump and his supporters are loudly claiming that the coming election is illegitimate if they don't win. There hasn't even been a single hint of this attitude on the Clinton side so don't give me this both sides garbage. 

"Both sides" are the magic words in todays politics. Its how a reporter can say Trump's refusal to release his taxes is bad but on the other hand Hillary didn't tell us she had pneumonia for 2 days so...both sides.

Both siderism has killed journalism.
