Our country was founded on the principle of a limited, constitutional federal government. This means the role of the federal government is meant to be limited to a few, well-defined and enumerated tasks. All other powers are supposed to be left to the states and to the people themselves. This principle is made clear in the 10th amendment.
In recent years, the political parties have brought more and more policy decisions to the federal level, attempting to solve every problem with a national policy. The problem is that people and states have different values and beliefs about a great number of issues. In reality, there is no reason we all have to do things exactly the same way in every state, county, or community. That's what is great about a constitutional republic. People can be tolerant of each other, and we can all do things our own way.
Our country is more divided today than at any other time, perhaps since the Civil War. This is a direct result of politicizing each issue, and then elevating it to the federal level. We need leaders in Washington who can step outside party politics and return our country to its constitutional roots: a limited federal government, which guarantees basic human rights to all its citizens, but otherwise defers most policy decisions to states and communities to decide for themselves.
