Historically 1 in 10 doesn't really mean anything, especially in light of that Hillary 08 number. Listen, you are just gonna get those Jon Tron people who liked Sanders, but ended up turning into Trumpsters. If you hate Sanders, I suppose this will help your hate boner, but a statistic like this isn't significant, at all. It won't help in the next election or give us any valuable insight (except, maybe, on defection as a whole). The only significant ones are like the ones in Michigan where Hillary lost Detroit in enough numbers, compared to Obama, to lose the whole state. In the end, Pennsylvania, Michigan, and Wisconsin, were the states that got Trump into office. Trying your hardest to compare Bernie supporters to Trump supporters is just gonna get the 90% that stayed mad, and hurt us in the end.
