Vote only on issues
Years ago, my wife and I lived in Northern California. A member of our church ran for Congress, and everyone was excited that someone who shared our values and beliefs was running.
He was elected. After he was in office and began voting on issues, I discovered that he and I had nothing in common but membership in the same church.
Now, I look at voting records on issues that are important to me and vote accordingly, regardless of church membership, military experience or anything that could make you feel connected to the candidate. Once the connection and the excitement wear off, you are left with someone who may not represent your views.
If you vote on a candidate's record on issues, you get what you expected.
