Political candidates are filing their last minute paperwork to take part in the May 29 primary.
The state added four new congressional seats and in two of them minorities make up the majority of voters.
Democrats are expected to win both of those seats, one in the Dallas Fort-Worth area and another centered on Brownsville. Republicans are also expected to add two members to the Texas delegation to Congress.
There will also be significant turnover in the Legislature in 2013. At least four out of 31 senators are retiring and at least 17 out of 150 representatives are not running for re-election. All of the departing senators and 10 of the House members are Republicans.
The close of business on Friday is the deadline for politicians to register to run.
