Senate District 18

Back when this district was first established, it was in Bexar County and held by Jose Antonio Navarro.  Nowadays this district is more southeast, comprised of a number of counties in between Houston and San Antonio.  Think Victoria County and it's surrounding counties.  For most of the 80s, this seat was held by Democrat John Sharp until he was elected Railroad Commissioner.  After Sharp came Democrat Ken Armbrister who kept the seat until his retirement in 2006.  Republican State Rep. Glenn Hegar then won the already Republican seat.  This was one of those areas of state the voted Republican up and down the ballot, but if an incumbent Democrat was conservative enough (i.e., Armbrister), they might keep him around for a good while.
