Just go vote with your gut in your local primaries.
If what works for everyone else reflects your personal vote, then you will be heard. Politicians are paid to make EDUCATED decisions, and their paycheck is on the line if they don't succeed. Just remember that 3/4 people in this nation have conservative views whether they're democrats or republicans. Kerry's record is self-explanatory, and he's not capable of uniting this country in any way. Ask his comrades and fellow senators.
