I take it this Diane Feinstein's not overly popular then?! Not a very clever situation all round really.
In the USA, we have two legislative bodies in the Federal Government, with popularly elected members from the individual states.
1. The Senate where each state has two Senators, six year terms that are staggered so you don't vote for both at the same time, statewide elections.
2 The House of Representatives, where the states have membership based on their relative population, Representatives have 2 year terms, and a Representative is elected from geographical districts that are determined by each state and normally set each decade after our census. For what it's worth, California's most notable (maybe notorious?) Rep is Nancy Pelosi, also a Democrat.
