Whole books have been written about the lies the right tells and why people in this country swallow them whole. Al Franken's Lies and the Lying Liars Who Tell Them: a Fair and Balanced Look at the Right is well worth reading - and funny to boot. Thomas Frank's What's the Matter With Kansas: How Conservatives Won the Heart of America is a highly readable account of the bait and switch that turned populist states to the right. Republican lies got us into the war in Iraq among other disasters. Currently they are lying when they claim to care about reducing the deficit, which would have been reduced significantly if they'd gone along with the law they passed another time they were in the majority that gave huge tax breaks to the wealthiest Americans on the condition that those tax breaks end after 10 years. They lie when they say they are in favor of reducing government, as they do their damnedest to continue and increase governmental interference in the lives of gay men and lesbians, and women's health care choices.
Once in a long while they admit to lying. Jon Kyl, Republican senator from Arizona, brazenly lied on the Senate floor, claiming that "well over 90% of what Planned Parenthood does is abortion." This was said in support of defunding Planned Parenthood, which receives some federal money that - by law - cannot be used for abortion services.
Abortion is actually about 3% of Planned Parenthood's operations. There's a good chart here showing what they really do: http://www.washingtonpost.com/blogs/ezra-klein/post/what-planned-parenthood-actually-does/2011/04/06/AFhBPa2C_blog.html. That baldly false statement of Kyl's was the unsubtle, overt lie. Of course there is also the more insidious, implicit lie, in saying that the federal government needs to defund Planned Parenthood to stop them from using government funds for abortions, when they use none for that purpose.
In a refreshing and unusual bit of candor, Kyl's office did retract the overt lie, sort of. They released a statement that what he said "was not intended to be a factual statement." Of course it wasn't. The Republican war on women's control of our own bodies is conducted mostly in lies. They lie every time they say they want to reduce abortions while at the same time trying to prevent women's access to contraception. They lie every time they talk about defunding federal government support of abortion when it already happened. They just don't usually admit it.
