First off, let me state - whether or not we agree, I respect your right to your opinion. I admit that I can be wrong, and I may very well be wrong in this instance.
That being said, I think your definition of fanaticism is different from mine, but let's look at what the dictionary says:
fanaticism: fanatic outlook or behavior especially as exhibited by excessive enthusiasm, unreasoning zeal, or wild and extravagant notions on some subject
Based on the definition, both a Trump supporter and an Obama supporter can be a fanatic. In fact, among people I know, I have known more Obama supporters who were fanatics, which is easy to understand as Obama is naturally charismatic and charming while Trump is a d*ck, but some people do admire d*cks. I have yet to meet a Biden supporter who was a fanatic.
A fanatic Trump supporter is the one who will support him even if he shoots someone on Fifth Avenue, to paraphrase something he said. A fanatic Obama supporter is the one who sees him as some modern day Messiah, who feels the tingle down his leg.
In both cases, rationality has gone out the window and emotion rules. It's like the teenagers who swooned over Elvis or the Beatles or whoever.
My friends who supported Trump were not fanatics because they admit to his flaws - they don't idolize him. They voted for him because they supported more of his policy ideas than his opponent's, even if they personally dislike him. That is a rational viewpoint.
Whereas a fanatic will refuse to acknowledge the candidate's flaws (whether Trump, Obama or whoever), will defend them even when it makes no sense and will call you names and go off the deep end when you point out their idol's flaws.
If all you have is a blind hatred or adoration for someone then you are being ruled by emotion and not rationality.
I don't vote for whichever candidate makes me feel better or who I like better. I carefully read the policy statements and go with the one I think aligns better with what I think is best for the country. One reason I voted for Andrew Yang in the primary. His ideas seemed very forward thinking and I thought he would make positive change. Unlike Biden, under who I don't see positive change occurring. I also thought Bernie or Elizabeth Warren would have been agents for positive change, unlike Biden.
Under Trump, if we ignore the tweets and the chaotic personal life and crazy statements and look at what he actually did - unemployment under Trump (especially among blacks) hit lows. Trump did not get us into any more foreign entanglements, which unfortunately we had with prior administrations including the disastrous Arab Spring under Obama. Trump also helped get the treaty signed between Israel and several Arab countries. All of these are good things. However, Trump muffed the response to Covid though he did start the Operation Warp Speed for the vaccine.
Similarly, there were both good and bad things about Obama's administration, about Bush and Clinton, etc.
Now if you disagree with me - that's great, and I look forward to hearing your rational arguments and factual response. If you can make a cogent argument for your viewpoint based on facts, I can be persuaded to agree with you.
If all you have are emotional statements - I don't want to hear it.
