Rasmussen used Likely Voters, a more expensive but more accurate method of capturing the electorate's mood than the Registered Voters polls. The expense comes in targeting the calls. You call 1,000 registered voters to get 600 likely voters rather than calling 600 registered voters.
Registered Voters polls are biased toward Democrats, historically. All the other polls in the Real Clear Polls Average are RV polls.
Polls in June are as meaningless as baseball standings in June. A year ago, Trump was under five percent. But the press plays this up because they want to stop the Trump Express, and in their hearts they fear they cannot, because they cannot.
Have faith. A year ago, they wrote him off. From my chapter on Nate Silver -- the media's Official Polling Guru -- in my book, "Trump the Press":
“Basically Trump is the Nickelback of presidential candidates. Disliked by most, super popular with a few,” Silver tweeted on July 15.
A month later on August 6, the Baghdad Bob of the army of the Goliaths, wrote, “If you want absurd specificity, I recently estimated Trump’s chance of becoming the GOP nominee at 2 percent.”By August, Trump dominated the polls.
Nate Silver is an anti-Trump liberal.
Worse, he was and is wrong, now giving Trump a 20 percent chance.
Do not believe him.
Buy my book instead :)
By the way, I received the print proof on Tuesday. It looks terrific. No typos. None.
And I autographed it and sent it to Mister Trump.
Please purchase my book "Trump the Press" through Create Space, as I get a larger royalty. It is a subsidiary of Amazon. The book will take a few days to be listed on Amazon, likely July 8. I have no control over that.
Also, please post a book review on the Amazon site. That helps attract other readers.
They have begun work on the Kindle edition.
