A Congressperson will want to be on a Committee that directly affects the citizens in their district.
Take for instance my representative, Chellie Pingree. Rep. Pingree represents the 1st Congressional District in Maine, which has a lot of lobsterman, farmers, and the big city of Portland that is trying to attract jobs.
Rep. Pingree will want to be on Committees that deal with marine and agriculture issues and also with economic development issues. She will want to be able to advocate and represent her constituents on the issues that face them and the best way to do that is on committees that deal with issues that face citizens in the 1st district in Maine.
A representative for Brooklyn, despite loving food, might not want to be on the agricultural committee as it wouldn't benefit their citizens and they would not be able to effectively represent their constituents.
