If you go to the the RCP averages, they show Cruz doing much better against Hillary than Trump. Now maybe you think there are reasons to discount that, but again, that's not the point. The point is that it is an objective enough basis so that you can understand why those numbers make a lot of people nervous.
If you want to blame them for being gullible when it comes to polls, fine. But I think their fear of a November disaster is very real. The biggest flaw I see in the pro-Trump theory is an over-reliance on white, blue collar voters, especially males. Republicans have been winning that demographic for a long time anyway. Obama only won 39% of the total white vote as it was. The second biggest flaw is confusing voter intensity with total numbers of votes. An enthusiastic vote counts no more than an unenthusiastic one.
Anyway, everybody has their theory, and maybe Trump can win. But the polls, which are the most objective evidence we have, say it is a real longshot.
“But the polls, which are the most objective evidence we have, say it is a real longshot.”
We are on the verge of winner take all states, Trump is ahead of the delegate target, Cruz is well behind with little chance to recover, and you believe the RCP polls are the “most objective evidence we have”. Nonsense.
