Because they didn't want to be called racist.
Thank you, but this is your opinion only and not an established fact. Do you suppose that Rush Limbaugh, Ann Coulter, Newt Gingrich, Sean Hannity, R. Emmett Tyrrell, House & Senate Republicans, Republican state officials, etc etc etc etc were also concerned with being called racist?
Nary a conservative of repute has lent this any validity whatsoever, yet two hack attorneys, Berg and Donofrio are just so exceptionally astute and doggedly determined that they are to be believed?
