You might be surprised. I for one am probably going to do something this November I've never done in my life -- vote for Trump. Not sure if this will get downmodded, but let me explain some of the reasons why, in no particular order.
1. The economy was much better under the last Trump administration than it is now. I'm not sure if it is coincidence, but somehow the economy under Trump actually worked. The current administration is just obsessed with spending larger and larger amounts of government money in an effort to curry favor with the voters, but that just leads to more inflation.
2. I know it is somewhat cliche, but yes the border is a factor. Strict adherence to the law isn't always good, and our immigration system probably needs some changes, but we do need to control immigration and cannot just let anyone and everyone cross the border. Immigration in small numbers is generally good. Too much, though, will overwhelm the culture of the host country. Finding that balance is hard, but I think the current Biden approach is too far.
3. Media lies. The mainstream media in this country has been consistently pro-Democrat party, and very much anti-Trump. Going back to 2016 when they pushed the fake Russian collusion conspiracy theory, to 2020 when they hid information on Hunter Biden's laptop and generally convinced me that Biden was just a nicer person than Trump (I now think they are both pretty average with some good and some bad). More recently, the media was definitely complicit in covering up Biden's unfortunate mental decline. Basically, they've burned a lot of bridges with me, to the point that I don't really trust them much more than the average Twitter (or /.) post. They could be right, but they could also be wrong or just plain lying.
4. Democrat party pushing censorship. This one really cinched it for me. For a long time the Democrat party has been very anti-2nd amendment (anti gun ownership). I'm not very comfortable with only the government owning all the guns, but it wasn't a deal breaker for me. But now they are coming after free speech, which is. Kamala Harris recently talked about needing to limit some people "free speech privileges". She doesn't even believe Americans have a free speech right, just a "privilege". The Democrats feel the need to control what people hear so they don't think the wrong things. This just isn't acceptable to me, and I cannot vote for any Democrat while it is true.
5. Somehow, the Democrat party has become the party of the rich elite and the Republican party has become the party of the working class. Also, the Democrats are pro-war and the Republicans are anti-war. Weird.
6. The Democrats in general put way too much emphasis on a person's skin color or gender. Kamala Harris is only the VP because Biden promised to select a black woman to be his VP (way back when he was running against Trump). She was not as qualified as other people, but she had the right skin color and gender. I grew up at a time when everyone was equal was the mantra, so that influences how I look at the world, and I try to look at people as people, not diversity quotas. btw, Biden's mistake was saying out loud his intention to select a black woman, as that forever characterized his selection by that.
7. Kamala Harris herself. She has not impressed me with anything she has said or done. Doesn't mean she would necessarily be bad, just that she isn't impressive herself. There is no reason to vote FOR her. And I suspect most people are voting AGAINST Trump than FOR Harris.
This post is getting long, so I'll wrap it up. This is entirely my opinion and how I see the world. You may disagree, and I suspect many will. There are lots of things I don't like about Trump (I don't think the environment will be improved under him, for example), but on balance I think he is the better candidate.
