14 Years

14 years.  Unless someone else files on Dec. 9, this will be the first time Democrats have had 2 elected officials running for executive statewide office since 2002.  Democrats have had elected officials run for the U.S. Senate and the statewide judiciary, but it has been 14 years since at least 2 incumbent officials have attempted to make the leap to one of the statewide executive offices (Gov., Lite Gov, AG, Comptroller, Land Comm, Ag Comm, Railroad Commission).  Just to be clear, when I say elected official I mean someone who is currently in office and running for another.

We've had former officials run in the past:
2010 - Bill White and Hector Uribe
2006 - Chris Bell, Fred Head, VaLinda Hathcox
2002 - John Sharp and Kirk Watson

Elected officials who ran:
2014 - Wendy Davis and Leticia Van de Putte
2002 - David Bernsen and Tom Ramsay

If Sen. Carlos Uresti had filed for Attorney General, we could go even further back.  The last time Democrats had at least 3 elected officials try for statewide executive office was 1998: Garry Maruo, John Sharp, Richard Raymond, and Pete Patterson.
