Will Rick Perry run for an unprecedented fourth term? We should find out Monday.

The Texas governor sent out an e-mail Tuesday inviting friends and supporters to join him in San Antonio on July 8 for an announcement regarding his "exciting future plans."

The e-mail was first obtained by CNN.

Perry was originally planning to announce his intentions by this week. But he delayed that decision after calling with a new special session to deal with abortion legislation that Democrats filibustered last week.

That filibuster might end up helping Perry's political career, whether or not he runs again. Already the longest-serving governor in Texas history, he's widely seen as ready to retire as Attorney General Greg Abbott (R) appears to be gearing up for a bid. But Perry has always been unpredictable, and he clearly wants to stay in the political arena.  Another presidential campaign might even be in his future.
