I voted "opinion toward dems changed" - no surprise there. I've commented frequently that over the past three years the behavior and attitudes of Dems, or more broadly - the left has morph so hugely that I could earn a PhD in Abnormal Psychology just be writing a dissertation about it. even after three year I'm still incredulous about the changes in lefties.
First, a personal anecdote. I came to DP from another forum that was slowly imploding. I had posted on it for almost ten years. One of the cool aspects of the forum was that the posters occasionally got together IRL at the beach or at someone's house. That died out after a couple of years, but I had the idea of holding "Forum Summits" a couple of times of year so I proposed a get together at a local microbrewery. Four peope showed up - equally divided by left and right slant. We had a great time, staying almost 3 hours. A few months later I proposed another summit and a 5-6 folks showed up and again we all had a great time. over the next couple of years we had a few more get togethers with attendance between 6 and 10; several survivors of the forum are among us here on DP. As we went on I struct up a relationship with a nice lady of the left which continued over the next few years. Then Trump happened. Almost over night my lady friend turned distant if not hostile; suddenly I was an alt-righter, or white supremacist or worse. She started sending me looooonnnnnggggg emails about why I was not only wrong, but unpatriotic, immoral and a Russian dupe. Her metamorphosis occurred over a few months; I had to ask her to stop e-mailing me and I blocked her phone number.
Regretfully, I've seen the same Dr Jeckyll/Mr Hyde change on several other of my liberal threads. All rational thought is gone, The word "Trump" causes involuntary mental dystrophy, unfocused anger and irrational striking out.
I thought the further we got from the election the more likely rationality and reason would re-emerge; boy was I wrong. The exact opposite occurred. The left just seems to get angrier, more emotional, and less rational.
To be fair, I've seen change on the right as well. From the day Obama took office, the mainstream Republicans have been telling us if we voted for them they'd get Obama under control' they lies, repeatedly. In 2010 we gave them the House back and took away the Dems filibuster proof majority - nothing much happed. same in 2012. In 2014 we gave them the Senate AND the House, but the mainstream GOPers were still more interested in "good ol' boys club" and "going along to get along" to make real change or progress.
Then Trump happened; he wasn't interested in good ol' boys or how "we've always done it". He encouraged the right to grow a pair, speak up and demand things get fixed. That's where we are today. Many on the right abandoned the Timex mentality ("takes a licking and keeps on ticking"). We struck back, spoke out, forcefully when necessary.
