As a long-time Kerry fan and supporter, I could go on at length, but I thought it would be better for you to read about his policy stands for yourself.

Take some time, read what he has to say - you really need to go into the detailed descriptions of his policies- and decide what you think of him.
Personally, I think Kerry represents an opportunity to restore honorable, dedicated and insightful governance in the White House. His experiences and knowledge give him a pool of resources that no other candidate, including President Bush, can match. His stands on the environment and intuitive thinking on education and job creation will help lead this country to prosperity. His extensive foreign policy background and commitment to making the U.S. a true leader in world affairs will help to ensure that we have a safe and respected nation.
Individuals who know him, regardless of political affiliation, have a great deal of respect for him. A local businessman who is a major fund-raiser for Bush was recently quoted as saying that while he certainly hopes and will work dilligently to ensure that President Bush remains in office, if he wakes up the day after the election, and John Kerry is president he won't lose any sleep.
Let me know what you think.
