Donald's two strongest devices are logical appeal and factual evidence. "Democratic crime policies, education policies, and economic policies have produced only more crime, more broken homes, and more poverty." This is logical appeal because following this sentence is the evidence to support the claim. The evidence is; "Last year, killings in this city increased by 69 percent, plus another 634 victims of non-fatal shootings. 18-29-year olds accounted for nearly half of the homicide victims. The poverty rate here is nearly double the national average. Almost 4 in 10 African-American men in Milwaukee between the ages of 25-54 do not have a job. Nearly four in 10 single mother households are living in poverty. 55 public schools in this city have been rated as failing to meet expectations, despite ten thousand dollars in funding per-pupil. There is only a 60% graduation rate." This evidence backs up the claim that the Democrats produce more crime, reduced education, and poverty therefore it makes the claim logical appeal.
Donald Trump's two biggest fallacies are name calling and assertions. He makes several assertions about Hillary Clinton and the democratic party. For example," The Democratic Party has taken the votes of African-Americans for granted. They'be just assumed they'll get your support and done nothing in return for it." He also name called multiple times. "We've seen the corruption of Hillary Clinton." Both of these fallacies harm his argument.
Obama's main argument is that every citizen deserves security and dignity; and that freedom must be secured by the people . He said that a great nation must care for the vulnerable and protect its people form life's worst hazards and misfortune. And when times change humans must adapt as well, and preserving our individual freedoms requires collective action.
Obama's strongest devices are diction and logical appeal that made the content more relatable to the audience. "We are true to our creed when a little girl born into the bleakest of poverty knows that she has the same chance to succeed as anybody else." He also utilizes emotional diction to sway the audience to his position. The example of logical appeal is; "Together we resolve that a great nation must care for the vulnerable and protect its people from life's worst hazards and misfortune." The appeal indicates the argument makes sense.
Obama's worst fallacies are assertions and emotional manipulation. Both of them damage his argument and make him less reliable and alienates the audience. An example of emotional manipulation is, "We recognize that no matter how responsibly we live our lives, any one of us at any time may face a job loss, or a sudden illness, or a home swept away in a terrible storm." He also makes several assertions such as; "We know that America thrives when every person can find independence and pride in their work." There aren't any facts that support his claim.
