Lots of reactivity here. If you feel that being one of 650,000 people represented by your representative allows your "voice to be heard", good enough.

Obviously the answer is to make the country's population much smaller. ;-)

A larger Congress is unlikely to make the country better. As long as the redistricting process makes most districts "a sure thing" for one party or the other, your voice (w/o some monetary "lubrication") is unlikely to be heard no matter the number of constituents.
