Student loan interest rates are set to double within a week if no action is taken by congress. In addition to calling your elected representative on this issue, you might want a more direct approach - call the Exxon Mobil lobbying office in Washington DC.
If you haven't noticed, Exxon Mobil has been running a national advertising campaign purportedly supporting an education initiative, the National Math and Science Initiative. These advertisements run nightly on cable TV.
Since Exxon Mobil is advertising that they support higher education, wouldn't it be logical for them to have their Washington DC Lobbying Office on K Street call their congressional minions, and ask them to pass the bill that would keep student loan interest rates at the current level? The person to call would probably be Theresa M. Fariello, the Vice President of Exxon Mobil's Washington Lobby Office.
