What it says is that the undecided voters are falling in the Clinton camp, and that Clinton has a strong lead in the polls. If all the votes fell 50/50 Democrat/Republican at this point, Clinton would still have about a 5% majority. If all the votes fell third party at this point, Clinton would still have about a 5% majority. About fifteen percent of the electorate is undecided at this point. Clinton has about a 5 point lead. Trump has to pull in undecided voters by a two to one margin in order to make the election close. That would require an impressive turnabout of public sentiment at this point. Also consider: this clip has existed since 2005. It's been in somebody's Avid for ten years. And there's a debate day after tomorrow. Who the hell runs this shit on a Friday afternoon... ...unless you're trying to make the whole Alicia Machado gambit look like a warmup act? The debate is going to be interesting.
I was curious why this was released on a Friday.
