How did the Vietnam war affect the outcome of the election of 1968?I need three supporting details.

As with the previous post, check a textbook or class reference for an answer to this.  I would say that the Vietnam War impacted the election hopes of President Johnson in 1968, as he decided not to run again for the office of President, convinced that he would not win reelection from his own party.  The issue of Vietnam, at this point, injected other people into the discussion of Presidential aspirations.  I would indicate that the Vietnam War significantly affected the candidacies of Eugene McCarthy, who posted a sizeable showing in the New Hampshire Primary, convincing President Johnson to not seek reelection.  It also allowed Senator Robert Kennedy to enter the political fray, appealing to the youth vote in that he was going to end the conflict in Vietnam.  Finally, the Vietnam War impacted the election of President Nixon in 1968 because, with the death of Kennedy via assassination, and the belief that the Democrats could not navigate their way through a convention, not to mention the Vietnam War, Americans became convinced that a Republican like Nixon was needed to ensure that America could reassert its rightful place in the world with a sense of dignity and with the belief that peace can be sought, but "not at any price."
