Thanks, Watermelon.
Also, it's important to note that MoE applies to subsamples, as well. You'll occasionally get polls with quirky demographic results and that's in the nature of sampling. "Unskewing" these polls interferes with the process of collecting a ton of data where the noise averages out. That's not to say I'm against weighting -- I just think this is a silly exercise to do with every poll.
Did my un-serious-ness come across? Guess not.
There's not much to take away from this poll other than a close race.
Sorry, wasn't really specifically responding to your post. Your point was totally valid -- that even with a hard weight this is still a slight Sanders lead
