The wrong question

MSNBC's David Shuster to NBC deputy political director Mark Murray:

Sarah Palin again repeating that line about ‘thanks but no thanks' on the bridge to nowhere, despite all the media reports that said she actually supported the bridge.  She's claiming again about the plane being on eBay although in fact it wasn't sold on eBay.  Explain what the political benefit could be for Republicans to essentially say "you know what, we don't care what the media thinks, or says, we're just going to have her repeat these lines anyway."

Seems like it's about time for the media to start asking if there is a political danger for Republicans if they keep lying, doesn't it?
