Looking for new info at bencarson.com So far, only Dr. Carson's statement on March 2nd:
I have decided not to attend the Fox News GOP Presidential Debate tomorrow night in Detroit. Even though I will not be in my hometown of Detroit on Thursday, I remain deeply committed to my home nation, America. I do not see a political path forward in light of last evening’s Super Tuesday primary results. However, this grassroots movement on behalf of “We the People” will continue. Along with millions of patriots who have supported my campaign for President, I remain committed to Saving America for Future Generations. We must not depart from our goals to restore what God and our Founders intended for this exceptional nation.
