IIRC, polls had Romney winning by 5 points the last week of 2012 election. That's not to say I disagree with the notion that there is a silent majority that will come out in droves to vote for Trump, because I do think that will happen. I do think the polls are off/skewed, etc....but I don't know by how much.
1. The Evangelical voters would not vote for Romney as they believe Mormons are the devil. We do not have that issue this time. If Romney had been a Methodist he would be president.
2. I have a Trump sticker on my car. I wear a Trump hat. So far no one has bothered me. I saw one other Trump sticker on I-70 yesterday. I have seen only one Hillary sticker.
