While it is OK to give citizens standing to challenge a candidate, the primary responsibility should be on the Secretary of State. These officials need to do their job, make a determination of eligibility, and strike the name of anyone who is ineligible. When Obama had his April 27th news conference, he took on ownership of a document which is now determined to be fraudulent. Probable cause to believe he is a felon is clearly sufficient to remove his name from the ballot.
The problem is they did not do their job and then let the courts say that citizens have no standing. I think it could be a conspiracy.
