Blinded by Partisanship

Sorry DeWrong, but Palin is actually right about this. Either she means her statement as a description of the past, or of what is happening right now. Most likely she was referring to how Fannie and Freddie have cost taxpayers money so far, as they are exempt from many taxes that a similar, privately-founded, company would have to pay. An alternate interpretation is that, just now they "have gotten...too expensive to the taxpayers", as there is a significant probability that they will require an outlay of cash from the government, which, if nothing else, hurts the government's credit standing right now and thus raises the rates it borrows at, and thus costs us taxpayers.
