A federal court in San Antonio approved an agreement today extending the filing period for the 2012 election. Since candidates have no way of knowing which district in which they will be running, the court also signed an order residency restrictions. Democrats and Republicans came to that agreement Tuesday, as part of the ongoing legal battle surrounding redistricting maps.

Candidates who file now will have the option to switch their district, or to withdraw their application once the final maps are released. Questions over where candidates will run and who they will face abound, and it is posing a challenge to candidates like Congressman Lloyd Doggett.

The original maps drawn by the Texas legislature pitted Doggett against State Rep. Joaquin Castro in a democratic primary. The interim maps released by a San Antonio federal court separated the two candidates into their own districts. With the latest developments, however, Doggett said Tuesday he will focus his time in both his current district and the interim district.

Doggett said "I don’t know where the lines will be, and that’s not only a personal impact, on me, but it’s an impact on citizens throughout our area, not knowing where there member of Congress might be located."

Doggett also told our Washington D.C. Bureau that he is concerned that a split primary would affect voter turnout and would be a financial burden to the counties.

Watch the video below to hear more about Doggett’s views on redistricting, as well as his take on U.S. Attorney General Eric Holder’s speech at the LBJ Library last night.

We did reach out to Republican Congressman Michael McCaul for his reaction to the latest developments. He declined to comment.
