BTW - I donated to Keyes campaign when he first ran some years ago. That was before I realized that he is a professional candidate, who runs to make money.
If Obama was determined to be ineligible Keyes would have picked up some votes, which would have qualified him to appear on more ballots the next time he ran.
The reasoning used to deny him standing is that unless he could win the whole enchilada this time, he suffers no injury even if the whole electoral process is corrupted. That denies the right to equal protection and due process, but it’s also facially incorrect because Keyes DOES suffer real and tangible injury if his ability to get his name on ballots in the future is damaged by an ineligible candidate being allowed to run and/or win.
So your own investment that you made is being neutered by this whole farce of an electoral system.
