I am happy to see incumbents go, of either party. If Dems kick the incumbents out of their party, and the Repubs kick them out of theirs.... maybe, just maybe, we'll get less fucking corrupt bastards in Government - regardless of party.
Anyone who thinks that these guys actually act in your best interests is a fool. They're playing us for idiots - and, sadly, we are allowing them to.
Sestak is an incumbent. Republican Pat Toomey has also served in Congress.
Ray Charles and Stevie Wonder know this is more of the same.
