This is really interesting to me. As I wrote in my first response, I didn't think this would hurt him much. I will also maintain that we haven't actually seen any polls yet, just media hysteria.
But I want to elaborate on my initial post. How is some "locker room" talk in any way worse than the despicable things that Trump has said in the past about muslims, mexicans, etc? How is this worse than Trump clearly demonstrating that he does not understand foreign policy? How is this worse than Trump wanting to "take the oil" from Iraq and clearly not understanding the dangers of starting a nuclear war? How is this worse than Trump claiming that global warming is a hoax perpetrated by the chinese?
It has been painfully clear to anyone with half a brain (sorry, Seriously) that Trump is historically and uniquely unqualified to be president. That the idea of a Trump presidency threatens western civilization itself. That any decent person has a moral obligation to vote against Trump.
In that context, a clip of him talking locker room sh*t seems very "meh". Who on earth is truly surprised by this? Trump has been married three times and has had affairs. Trump has cultivated a playboy image. He has appeared in soft porn movies. He has said offensive things about women numerous times.
Sure, if this can get some of the people who have been in denial about Trump to realize what kind of a person he is, then I'll take it. I just seriously doubt how many of those people are actually out there. I have a hard time imagining his supporters actually abandoning him over this. All that we have seen so far is elected republicans who have images and careers to look after, that have critized him.
Don't get me wrong. I hope with all of my heart that this finally sinks him, but I want to see very solid polling data confirming that before I even start getting my hopes up.
EDIT: I should also add that I don't personally find this kind of trash talk all that offensive. I wouldn't talk like that myself, but I have certainly heard talk like this from people I have encountered - and have generally not taken it very seriously. If this had been Obama caught on that tape, it would not have meant that I wouldn't support him.
This largely sums up my reaction as well. The behavior he portrays was defined a long time ago. Most undecided voters are already conscious of who he is. I am very skeptical that there are more than a miniscule # of people that were at the cliff of voting for him and use the video clip as an excuse to not vote for him.
It's time to stop celebrating early by the presumption that this will sink him because his voters are here to stay for a long time and will persist whether he wins or loses the election.
