By the end of primary election day the 435,397 registered voters in Collin County had cast 54,901 ballots in the Democratic and Republican primaries for a 12.6% voter turnout.
5,676 of those ballots were cast in the Democratic Primary and 49,225 Republican Primary ballots were cast. 22,644 Republican ballots and 2,645 Democratic ballots were counted for Election Day - including vote by mail ballots. Between both parties a total of 1,640 vote by mail ballots were cast with the majority being cast for the Republican primary.
The primary took place under interim district maps ordered by a San Antonio federal district court earlier this year while the maps passed by the 2011 Texas legislature and signed by Gov. Rick Perry continue under "preclearance" review by a Washington, D.C. District Court.
Under Section 5 of the Voting Rights Act, Texas is one of eight states with a history of discrimination that submit congressional redistricting proposals to either the Justice Department or a D.C. court preclearance before they can take effect.
Texas Republicans are threatening redraw the redistricting maps during the 2013 Texas legislative session. GOP Primary voters approved their party's Primary Ballot Proposition #5 that reads, "Redistricting - The Texas Legislature should redraw the court-imposed lines for Congress and State legislative districts in its upcoming session in order to remedy inequities.
As did the rest of Texas, Collin County voters split their votes for the U.S. Senate candidates listed on the Democratic and Republican ballots.
