Americans are mostly centrist, when you come down to it. We may swing one direction, then the other, but for the most part things tend to stay fairly balanced. Candidates that are talking about green new giveaways make a lot of noise on the twitterweb, but that kind of talk doesn't resonate with unplugged Americans. We want to discuss, and resolve issues that affect our daily lives. That's why Trump won in 2016, and that's why he'll win in 2020...
So the Democrat candidates are all disconnected with the American people ... why?
I think it's the difference between pushing an agenda that's good for America, vs. pushing an agenda that's good for The Party. Even here in deep blue California my Democrat family and friends are no longer able to defend the Democrat's leadership. They are disenchanted with direction the party is going. They aren't socialists, they aren't sold on the Green New Deal, they know the difference between universal healthcare and socialized healthcare (or Medicare-For-All, as the media likes to call it.)
I also believe social media, and cable news have a divisive and polarizing affect on politics. It tend to attract the most extreme perspectives, while giving the appearance those views are more widely accepted. Social media does not provide an accurate representation of the larger American philosophy, and the MSM are more often wrong than not. It might seem like a ton of Americans do want "Free Stuff," but we are well aware of the pitfalls of handing over too much power to the government, and especially to one political party.
The American political landscape will balance it's self out, it always has in the past. During the Clinton administration the Republicans went through the same partisan extremism, and now they seem more like the rational and effective party of the Reagan years.
This is a very interesting point you make. It reminds me of the 2008 election, when Obama won his first term. Here in California we had measures on the ballot to allow gay marriages and to decriminalize marijuana. Both failed miserably.
A good friend of mine actually predicted that those measures would fail, and it was largely because of the demographic of voters who turned out for the election. This friend of mine is half Mexican, and has a lot Democratic family members who were very supportive of Obama. Knowing what he knows about the Hispanic community, he was confident that even though they are Democrats they are actually extremely conservative on social issues. It could be cultural or a religious predisposition, or likely both as they can often conflate. This friend also commented that Black Americans can also be very socially conservative, if not downright homophobic.
Being that the Democratic party, which often bills itself as "socially progressive," relies heavily on Black and Latino votes, I think this conflict will hurt Buttigieg's chances of winning the primary, let alone the General election.
I personally have nothing against someone's sexual orientation, and if I thought he would make a good president I'd vote for him. Like Lindsey Graham, for example. If Buttigieg does win, it's not like he would be the first gay president. I just hope history doesn't repeat itself...
