Great news! I'm very pleased to hear this, but... I'm not at all surprised. I think that most voters are starting to figure out BS and the BS campaign. They're rejecting his message and his lack of any real-world plans on how to accomplish all the grand promises being made. It's one thing to make promises, but it's quite another to demonstrate to educated, realistic, and discerning voters exactly HOW it is that all the promises are going to be kept.
Also, I think the almost nonstop smears and denigration of the Democratic party (and Democratic leadership) may have made BS a less desirable choice. At this critical time, party loyalty is very important to me and many others apparently too. It simply makes no sense for anyone on "our side" to be call the Democratic party "corrupt" or "feeble" or "the party of the elite" or saying there's "no difference" between the Democrats and the GOP. In all cases, nothing could be further from the truth.
The thing is... that kind of talk promotes negativity. Negativity generates apathy. Apathy discourages support and voting for Democratic candidates... and that just makes it easier for the GOP and Trump and Russia to steal elections.
