America was united in the wake of 9/11 - USA TODAY

The unenviable task of running against Reagan fell to former Vice President Walter Mondale. Mondale made two bold choices in his campaign, both of which backfired. First, he selected a woman, New York Representative Geraldine Ferraro, as his running mate. Media scrutiny of her husband’s finances put Ferraro on the defensive. Second, Mondale announced in his acceptance speech that he would raise taxes to fight the deficit. He missed the opportunity to point out that a day earlier Reagan had quietly signed a bill raising taxes by $50 billion. Reagan succeeded in tagging Mondale as a typical free-spending Democrat, and won the most lopsided electoral victory since 1936.

Most of Walter Mondale’s ads featured ominous music reminiscent of the soundtrack of the popular horror movie . To evoke the dark side of "Morning in America," these conceptual ads used eerie scenes such as a father digging a hole for a bomb shelter in his backyard to protect his family in case of nuclear war. Mondale’s ads attacked Reagan on three issues: arms control, the deficit, and the widening gulf between the rich and the middle class. The ads asked the public to look beyond the apparent prosperity of the nation and see trouble on the horizon, but their claims did not ring true for the majority of Americans. A Mondale citing Reagan’s foreign-policy failures, with images of the caskets of marines killed in Beirut, was ineffective because Reagan was not considered responsible for that tragedy. Ads that were meant to show Reagan as unfair to the middle class were negated by the irresistible imagery of the upbeat Republican spots. Attacking Reagan simply proved fruitless, and Mondale’s commercials never presented a strong vision of an alternative to the Reagan presidency.

Alternatively: it is impossible for the premises of a valid argument to be true while its conclusion is false.
All other arguments are invalid; that is, it is possible for their conclusions to be false even when their premises are true.
