Trump's arguments in this segment of the presidential debate, while emotionally charged, are largely invalid due to his reliance on personal attacks, fear-mongering, and unsubstantiated claims about Biden's presidency leading to the country's destruction. Notably, Trump fails to address the moderator's question about making childcare more affordable, instead focusing on unrelated topics and fallacious arguments to appeal to voters' fears and dissatisfaction.

1. red herring • Instead of addressing the question about childcare affordability, Trump launches into a tangent about a general who was fired, which is irrelevant to the topic at hand.

Just to go back. The general got fired because he was no good. And if he said that, that's why he made it up. But we have 19 people that said I didn't say it, and they're very highly respected, much more so than him.

Actually, Trump never discussed childcare at all during this entire segment of the debate that was supposed to be about childcare.

2. ad hominem • This statement attacks the person (President Biden) instead of addressing the argument or the issue at hand, which is about making childcare more affordable.

He is the worst president. He just said it about me because I said it. But look, he's the worst president in the history of our country."

One of a series of ad hominem attacks, it lacks any logical merit or relevance to the topics of the debate.

3. appeal to fear • This statement uses fear to try to influence the audience's view by suggesting catastrophic outcomes if President Biden wins the election.

If he wins this election, our country doesn't have a chance.

This is simple fear-mongering without providing evidence or directly addressing the childcare affordability issue.

4. appeal to popularity • Trump attempts to bolster his claims by citing unspecified polls and suggesting that his popularity is evidence of his good performance.

Just you understand, we have polling. We have other things that do - they rate him the worst because what he's done is so bad. And they rate me - yes, I'll show you. I will show you. And they rate me one of the best. OK.

This is fallacious because popular opinion doesn't equate to factual accuracy.

5. appeal to motive with false dilemma • Trump asserts that there exist only two possible explanations of Biden's intentions with his border policy, ignoring the possibility of other purposes or motivations.

He wants open borders. He wants our country to either be destroyed or he wants to pick up those people as voters.

This interpretation moves beyond simply presenting limited options (as in a false dilemma) to implying nefarious intentions behind those options, thus questioning the opponent's motives rather than addressing the argument's substance.

Alternative and more constructive motivations behind advocating for certain border policies could include:

1. Humanitarian Concerns: Aiming to create a more compassionate immigration system that respects human rights and provides asylum or refuge to those fleeing violence, persecution, or poverty in their home countries.
2. Economic Benefits: Recognizing the positive contributions that immigrants make to the economy, including filling labor shortages, contributing to innovation, and enhancing the cultural richness of the country.
3. Family Reunification: Prioritizing policies that help keep families together, acknowledging the importance of family unity in immigration processes.
4. International Cooperation and Responsibility: Working with other countries to address the root causes of migration, such as violence, climate change, and economic disparity, as part of a global responsibility towards more sustainable and peaceful international relations.
5. Legal and Systemic Reform: Seeking to overhaul an outdated immigration system to make it more efficient, fair, and aligned with current economic and social realities, thereby reducing illegal immigration by providing legal pathways.

These motivations reflect a broader and more nuanced understanding of immigration issues, focusing on long-term solutions, ethical considerations, and the overall well-being of both the nation and the individuals seeking to enter it.

6. straw man • This misrepresents President Biden's position on tax policy to make it easier to attack, implying a drastic increase in taxes for everyone which Biden has not proposed.

He wants the Trump tax cuts to expire so everybody, including the two of you are going to pay four to five times.

Although Biden wants to remove or reduce some of Trump's 2017 tax cuts, he has stated clearly that he wants the cuts to remain largely in place for those who earn less than $400,000 per year, which is the vast majority of taxpayers.

7. slippery slope with appeal to fear • Trump asserts that Biden's re-election will lead to the downfall of the entire country without providing sufficient evidence to support this extreme claim.

If he wins this election, our country doesn't have a chance. Not even a chance of coming out of this rut. We probably won't have a country left anymore. That's how bad it is.

Trump uses emotionally charged language ("our country doesn't have a chance," "won't have a country left") to make people afraid of a Biden victory.

He takes it further by suggesting that Biden's re-election will inevitably lead to a chain of increasingly negative consequences, culminating in the destruction of the country. This is a slippery slope because it presents a worst-case scenario without sufficient evidence to support the likelihood of those events unfolding.
