Imagine how much money is involved if the elites wish to buy off each and every member (545?) of the House of representatives AND they only get a two year window for their bribe. Now, buying off a US Senators is a much better deal. Not only are there only 100 total but also you get a six year window which is far more bang for your buck. Yes, there is corruption in all government but by having the State legislature elect the US Senator/ Ambassador to the Federal government, once again the possibility of corruption is reduced since the US Senators are elected by the most populous State House (how much money would it take to bribe enough Reps to get the Senator you wanted? And this bribe money would have to be paid in ALL 50 States). Also, think of this. The reason there is a two year election for Reps is because if you elect a bad apple, you can vote him/her out in two years. Six year term were given to US Senators so the State legislators were conducting the states business instead of holding elections every two years. If The founding Fathers wanted US Senators to be elected by popular vote, running campaigns and receiving donations from lobbyists, they would have also made them run for office every two years and not six, again in case of bad apples. Why do you think that: * Senators are not included in the Presidential line of succession?  * The Senate, not the House, ratifies treaties between the US and other nations? * The Senate, not the House, confirms Judges and major cabinet positions?
