most important issue in the upcoming election (other than the economy)

Moving America into the 21st century pretty much covers it.

Health care reform is THE big one; new tax codes without excessive burdens on the middle class; moving ahead with science and technology regarding alternative energy sources; new forceful regulations on banking and finance; other environmental issues, like more recycling. Repeal of NAFTA; immigration reform, higher standards for imports from China. Many people want the war in Iraq ended immediately. I don't think that will happen, but I'm not in charge of anything important, anyway...
