I heard two Kerry supporters reasons for voting Kerry the other day, and I could so quickly disarm them of their reasons that it was silly.
1: Because Bush unfairly taxed the middle class
"No he didn't, do you understand how a tax cut that unfairly effected any class would not be passed through congress? the cuts were even across the board."
2: Because of Kerry's stance on the Kyoto agreement
"Which stance? This August 19th stance or his August 24th stance? On Friday 19 August, the campaign issued a document aimed at keeping the West Virginian coal industry open. It included the words, "John Kerry and John Edwards believe that the Kyoto Protocol is not the answer. The near-term emission reductions it would require of the United States are infeasible, while the long-term obligations imposed on all nations are too little to solve the problem."
But on 24 August, The Journal Times of Racine, Wisconsin, published an account of John Edwards' visit to the town the day before. According to the paper, Edwards "lamented" America's failure to join the Kyoto treaty."
Those were the issues most important to them, and they didn't have the facts right. that is why people need to be informed, and they need to agree with a canidate on more than just one area.
