The US Supreme Court heard the oral arguments in the Texas Redistricting Battle on January 9th, 2012. If the Supreme Court does not make a decision soon then Texas might be forced to change the Primary election date again. Some of the elections would still be on April 3rd, 2012 and some would be pushed back to a later date. This is due to the fact that the State Republican and Democrat Party Conventions have to be in June or July. Those cannot just be cancelled. Hopefully the US Supreme Court makes a decision soon so that Texas can get things sorted out in time to still have all the Primary Elections on the same date in April.
It is hoped the Supreme Court will also rule that Section V of the Voting Rights Act is unconstitutional. Several states have filed Amicus Briefs in support of striking down Section 5. Basically, it is not constitutional that the Federal Government has one set of rules for some states and one set of rules for other states. Some states get to do what they want in redistricting and voter id laws but other states have to have their laws approved by the Justice Department (a biased, non elected federal entity).
