As for former presidents becominf legislators, I donno... Some probably have something left in the tank and might be helpfull... Think Jimmy Carter and possibly Bill Clinton here... But I wouldn't want Georeg Bush in either the Senate of the House and I don't think too many legislators would want him there eirher...

I kinda like the idea of Bill Clinton as a Senator, though... It would keep him busy and keep him outta Obama's hair...
