Texas Governor Rick Perry announced a special election for the currently vacant district six state senate seat. The position was held by Senator Mario Gallegos, who died last October but was nonetheless reelected posthumously in November.

The Governor has set the election for Saturday, January 26, 2013.

In the event a single candidate does not receive a majority of the votes in the January election, a runoff election will be held between the top two candidates receiving the most votes.
