Congress is certainly flawed, but I contend that it's the typical voter who is worthless.
How do you explain the fact the only 1/3 of Americans place any trust in Congress, yet so many of the incumbents keep getting voted back in year after year, decade after decade?
The average voter could get mugged and robbed by their congressperson (which figuratively happens all the time), but wouldn't be able to identify him/her in a police line-up. All it takes is one TV Ad the night before election that says "Vote for Joe Blow. He's in the know!", and that's who wins his 25th. term in Congress.
