Independent presidential candidate Ralph Nader has obtained enough signatures to appear on West Virginia's general election ballot in November.

The secretary of state's office announced Tuesday that an incomplete review of Nader's petitions shows his campaign gathered 15,302 valid signatures. That exceeds the 12,962 he needed.

Nader's campaign submitted petitions bearing 23,000 signatures last month.

Libertarian presidential candidate Michael Badnarik also has collected enough signatures to appear on the ballot. A review showed he had gathered 13,712 valid signatures.

The announcement comes one day after Charleston lawyer Jason Huber sued Secretary of State Joe Manchin. The lawsuit alleges Manchin failed to investigate how Nader's campaign obtained the signatures, or failed to refer the matter to the attorney general's office for an investigation.

Huber filed the lawsuit on behalf of five people who want copies of the signatures released to the public.
