See this about Nobel prize winner and voting methods pioneer Ken Arrow endorsing range voting as "probably the best" single-winner voting method in an audio podcast (we have audio recording).
Libertarian Party candidate for Colorado Governor Jaime Brown endorsed approval voting as a plank in his 2010 campaign platform. It also was endorsed by Republican Party candidate for Colorado Secretary of State Scott Gessler (as a plank in his 2010 campaign – note the SoS is in charge of elections) and he won the seat:
Local choice: Just as states can develop voting systems that fit their specific needs, local home rule entities should also have substantial leeway in voting systems. To that end, the state legislature should allow home rule municipalities and counties to develop voting methods that meet their needs, including approval voting and range voting.
– quoted from Gessler's campaign web page http://www.scottgessler.com/issues.htm.
[Gessler] would support local experimentation with what is called "approval voting," which allows voters to choose more than one candidate in a race. The idea is favored by Libertarians and other minor parties who often siphon votes from Republicans and Democrats. "That sounds crazy, doesn't it? But it actually works," Gessler said.

We seek endorsements from everyone in all walks of life. We also are especially interested in top scientists, editorialists, church leaders, party leaders, politicians, social scientists, professional pollsters, incredibly sexy celebrities, businesspeople, army generals, et cetera.
You may also "join" CRV (i.e. you might like to work for us in some way) which is different than "endorsing" it. (Do both!)
Fill in the blanks below. The only slots you must fill are your name, fame-number, and proof of not being an evil robot. All others are optional.
We recommend also putting a URL (if available) and city/state/country. Your name will come out hyperlinked to your URL on the endorsements page, if you supply a URL. If you supply an email address, that email address will be available for all to see on the endorsements page. If you don't mind people seeing your email address but are opposed to spambots, then use distorted syntax. We very highly recommend putting "impressive qualifications" like "1972 Nobel Prize winner in Physics," "Chair of the Democratic Committee of Georgia," "Governor of Alabama," "Author of *title here* social science books," "Episcopalian Bishop," "Professor of xxx at yyy," etc. Thanks!
Special note. If you are not a person but rather an organization like "The Libertarian party," or if your endorsement consists of an essay (or to ask questions), then please notify us of your endorsement by email to rangevote AT gmail.com instead of using this form. It would be even better to send it to RangeVoting at yahoogroups.com, except that you have to sign up as a "member" of this email-list in order to post to it, which some may not want to do. (Essay-style endorsements like Ossipoff's above enable you to word it exactly the way you want and to say something more individualistic; and it is fine to provide us with both kinds of endorsement.)
