Trump is making exactly the opposite arguments from what Romney made 4 years ago, Rip.Perhaps Trump will win, but "conservatives" are making the exact same arguments they made four years ago.
And doing worse.
No, that is merely your opinion he is doing worse.
There is an entirely different attitude toward him outside the Professional Political Class Echo Chamber.
Polls taken of Likely voters that include people who have never voted before show a 10%+ slide in Trumps favor over the polls that are of only Registered voters who voted in the last Presidential election. Using an a distribution of Democrats, independents, liberals, conservatives, moderates and independents that reflect the general population and Trump is still tight with Clinton, and that bodes poorly for Hillary. With her name recognition nad 30 years in the public eye, she should not have a close race with Trump at all.
Your analysis is nonsense, and you are doing exactly what Mac is saying you are doing. You are convincing yourself that it's closer than it really is because your candidate is getting crushed. There is no demographic of political affiliation. Most pollsters don't use it, and never have.
At this time in August of 2012, Romney was trailing by 4.5% in the RCP averages. Two weeks after the convention, he was trailing by 3.5%. Today, in August and two weeks after the conventions, Trump is trailing by 7.5%.
That is an empirical fact. But you won't believe it because you are convincing yourself of the exact same nonsense Republicans told themselves four years ago.
