I don't see what you have to apologize for. You've done a great job introducing me to the US politics so far, and I'm looking forward to learning more.

I have questions about what you've said by this point. I hope you don't mind me asking on. Some questions are without respective quotes - mostly because they're more general.

Every 2 years elections are held for the House of Representatives and one-third of the Senate

What those two bodies of government represent, and what is their respective responsibilities, in simple terms?

Why do only the two parties matter? Solely because they're the biggest (I hear a lot about them and barely anything, even in history, about any other)?

The Republican Party currently holds both the House and the Senate, but there's a Democratic president, Barack Obama.

What does the partition mean for the country's political atmosphere? What's those positions', party-wise, influence on the country so far - that is, for example, how is a Democrat president different from a Republican president? Does it even matter what party they are? Does it matter if the President is an unaffiliated person, parties-wise, and why if it does?

Only two states have held primaries so far (Iowa and New Hampshire)

Why do they hold the first primaries? Why is the order of the primaries as it is currently? Clearly, it's not alphabetical, and I don't have a map of the US to confirm that it's geographical.

Donald Trump is the odd one out here. On some issues he's an extremist (immigration), but on others he's more moderate or almost left-wing (campaign finance reform). He is by far the most anti-establishment candidate, which is what makes it so shocking that he's currently the frontrunner.

I shall pray for you, my friends in the United States, if this man gets elected as your country's President, because this promises to be a disaster. So far, I've heard nothing good about him, and from what I've seen of him personally (on the Internet), he's a terrible person to run the country and gives off a vibe of a terrible person overall. This is not someone to have the rule over one of the world's most military-equipped countries in the world... and I wanted to add "with an enemy that Russia is", but hearing from the recent article linked to on Hubski about the Russian state of affairs (from participating in the discussion of which I was banned by kleinbl00 - damn shame), citizens of US or their government doesn't really consider Russia an enemy - or, at least, an enemy worthy of fighting as much as the Russian propaganda leads us to believe. I'll ask about this through #russiabynatives: I'd like to get to know what the outsiders - that is, those outside Russia - think of or see Russia as.

[Hillary Clinton] has overwhelming support among Democratic elected and party officials.

What about the people? What does the general population think of her? I don't know of her political agenda or promises, but so far, she gives off a vibe of a person I'd trust to run my country had I been a US citizen.

Why do Republicans have so many presidential candidates? Is it because the last president was Democrat?

Finally, is it "president" or "President" in English?

Thank you very much for such a detailed yet concise report on the politics of the country I look up to.
