Probably giving MSNBC too much credit with these numbers, but the strategy here is:
1000 people see the poll showing O extending his lead.
10 people see the admission that the poll was skewed.
Net gain: 990 people still think O has extended his lead. To them, it’s worth it.
They do it all the time with every biased story and lie they tell.
You don’t seriously think that as many as 1,000 people actually watch MSNBC, do you?
