First, get rid of the Electoral College. So few people, especially young people, understand it, not to mention, it is an out dated system.
Second, be completely honest, even if it hurts your campaign. If you have a program or idea that will negatively impact some people but would benefit others, then say so. A negative, but truthful, statement is better than a promise that isn't kept.
Third, set term limits for all branches of the federal government. In a systems of checks and balances, is it right that the President is limited in the amount of time he or she can serve, but Senators and Representatives can continue serving as long as the people continue to elect them? It should be a consistent policy for everyone.
Finally, run younger candidates. People in thier 20's and 30's can relate to a young candidate, a candidate who is in his/her 30's or 40's, better than they can to a candidate who is 55+ years old. You have a completely different mindset, a different view of the world at 18, 25, 30 years old then you do at 50. This goes along with setting term limits for congress. Get the 60 and 70 year old people, that were first elected by our grandparents 25 years ago and still being elected by our grandparents today, out of office and get some new, young people into the government. If more 'young people' are in government, it would help to get more young people involved in the democratic process.
