I read both links.The second link has a number of comments but I did not detect any credible source that was able to kill off the results. My take is that even if the polling is off ten per cent which would be a lot its still a landlslide for Trump.
I would love to know your opinion of the poll.
I haven't heard the radio call in poll, but on the surface, if it is a hoax, it is more credible.
I wouldn't cite either poll for the proposition it claims.
All that said, I think the "official" polls are crap. Trump is doing much better than the news reports would have you believe. But we know the press and public are capable of pulling off massive manipulation. Obama was elected twice, with no credible history of connection the US (admitted born a dual citizen, admitted formative years in Indonesia), a bomb-throwing "community agitator" with nothing but cliches for rhetoric.
Even today, just now, CNN plays a clip of Obama remarking on Trump's "election is rigged" remark. Obama says nobody says there is cheating, until after the game is over. Oh? Never a complaint about bad call by the referee? Puh-leeze. Obama's logic on pretty much everything is totally flawed, but the press and probably half of the public accept it.
