The TIME Magazine of January 27 has this interview with Clay Mulford. Mulford was in charge of ballot access for Ross Perot. Michael Bloomberg had met with him earlier in the month, so TIME mostly asked Mulford about what Bloomberg and he had discussed.
The interview is somewhat misleading, because it says that Bloomberg would need 74,108 signatures in Texas. In reality, he would only need 43,991 if he accepted the nomination of any of the three Texas parties that wants to nominate him. Thanks to Earl Divoky for this news.
