According to this story, negotiations over the date of the 2012 Texas presidential primary are focusing on moving it to early April. An April presidential primary would automatically result in a late June petition deadline for previously unqualified parties, instead of a May deadline.

If the deadline becomes June instead of May, that would mean that all states in 2012 would have some procedure for getting on the November ballot for President in which the petition deadline was in June, July, August, or September. That would be good news for anyone who gets into the race late. However, in order to take advantage of the party petition deadline, the proposed new party must have filed a notice no later than January 2, 2012, with the Texas Secretary of State, saying it intends to qualify as a party.
