The following is an excerpt, by permission, from another and very fine blog, The Newsosphere (thenewsosphere.wordpress.com).
Romney recently said, and his ad claimed that "Obama approved Jeep, now owned by the Italians, of moving all production to China." This has already been disproven by a wide number of sources.
Let me direct you to the first Romney ad, which had Obama saying "If we keep talking about the economy, we're going to lose".
It was later discovered that what Obama actually said was: "Sen. McCain's campaign actually said, and I quote, 'if we keep talking about the economy, we're going to lose'."
Folks, enough is enough, and a lie is a lie. He [Mitt Romney] has been lying since the start of the campaign, and it doesn't look like he's stopping anytime soon.
Look, these quotes and ads up, people. Do your own digging. It's all there. I'm not taking anything "out of context".
I am fed up with this b*****t. If someone is proven - again and again! - to blatantly lie, why in the name of God would anyone want that person to govern our nation? End of excerpt
I just want to add a personal observation that while both campaigns have included errors and misstatements, the act of repeating deliberate inaccuracies, lying, is really a whole other thing, just as this excerpt so very clearly says.
