Trump Bombshell Speculation

[Maxwell]

Video of Trump talking about how he's fooling all the Republicans and how fast he'll dump them once in office

That would probably help more than hurt.

yeah anything trashing Republicans might even help Trump with Republicans.

It would also depend on the context of Trump using the n-word.

I think Luntz is very frustrated because he is something of a Republican hack - but to his credit he's being honest in what his focus groups and numbers show.

I can't tell if Luntz is actually hinting at anything or just saying that there is always another Trump scandal popping up.

Unless it's something like the N word, I don't know what will hurt him.  The sexual comments are already out there, so more of those won't do much.  Talking about Russia/Putin?  Most Americana are more outraged by sex/bad language I would think.  

Things that would actually hurt him at this point, IMHO:

*he's broke
*he's flat-out embezzling money from his campaign (more than he already is)
*he paid for an abortion for a mistress
*one or more videos of him gving insane racist or misogynistic rants
*video of him committing sexual assault (possibly against a minor)
*video/audio (maybe email?) of him conspiring with the Clintons or Russia
*he funded the 9/11 hijackers (likely unwittingly)

*he's self-hating gay been trying to compensating it by "being El Macho" with women (who knows?)

it would certainly explain his hand gestures and his way of speaking.
