From an outsider, who really can't figure out the US electoral system:
is it the President, who seems to be blamed for anything and everything, yet doesn't seem to have a party (or group) to support him?
or the House of Representatives, which seems to be the body who proposes legislation, yet doesn't seem to have the power to enact it?
or the Senate, which seems to have the power to block anything anyone else does, yet doesn't seem to be able to initiate anything?
or private enterprise (Big Business), which seems to spend an awful lot of money buying politicians?
Can anyone point me to a succinct explanation of how it all comes together? (as distinct from a treatise on how it's supposed to work, I mean.)
