Nice job, as usual! My suggestions (Some if not most of the following tweaks are merely stylistic):
Well... I'm from Brazil. Here, presidential elections are held every four years. After two consecutive elections / terms, a president can no longer stand for election / run for office. We have / see a lot of election / campaign material on TV, on the radio and so forth as it / the election draws near(er). We also have political rallies / gatherings / meetings everywhere, which some people love. They even fight over their parties / political differences. I think they are absolutely crazy, but the majority of the population just hates politics as well as the politicians themselves, who always promise good things for the people, but never do anything. That's it.
"Once elected twice" is not incorrect, but might raise a few eyebrows. To sidestep any confusion, adjust the wording so that "once" and "twice" do not occur in the same sentence.
Keep up the great work.
