According to SourceWatch, the League of American Voters essentially consists of Morris and one other staff member. They share an address with another ultra conservative front group, Americans for Tax Reform, and have overlap with organizers of Tea Parties. In other words, the league does not represent you and me - it really represents Morris (who is trying to sell his book), big pharma, health insurance companies, and right wing crackpots.
FactCheck.org says the league's ads are filled with buzzwords like "rationing" and "tax surcharge" and include a number of misleading claims - incorrectly stating future costs and asserting there will be a tax increase without saying that very few people make enough to pay it. The ads are running nationwide against Democrats in targeted districts like VA-05, which is represented by a courageous freshman incumbent.
