Well how do you -get- that kind of experience aside from being a U.S. Senator for that state? This is like the "I need a job, but I can't get a job because I don't have the experience." quandry.
Also how about Hillary Clinton -- she not only didn't have any legislative experience in New York, she didn't have any legislative experience ANYWHERE, and no government experience except being appointed by Bubba to preside over the health care socialization debacle - but the liberal press has been, oooooo, just tingly in the crotch about her since she took office, just like they always are when some non-WM liberal/left lawyer sticks his/her head up and runs for office. The blather about Keyes not having experience in Illinois is just a smokescreen - the attacks on Keyes have more to do with the special venom that liberals reserve for uppity blacks who dare to leave the democrat plantation, same with Justice Thomas' "high-tech lynching".
