I bet this has more to do with the 400 signatures from each district rule than, the signatures not being from valid registered voters.
I have not seen a satisfactory explanation of why all these names have been thrown out.
I find it impossible to believe that longtime politicians like Newt and Perry just submitted a bunch of bogus names thinking they could wing it.
It does not pass the smell test.
I thought I read that many of Newt signatures were completely missing adresses. That said, I think an equal protection lawsuit could at least force the verification of Paul and Romney petitions.
