FORT WORTH - Former Secretary of State Roger Williams and retired Army officer Wes Riddle of Gatesville jumped to the top of the 12 Republicans hoping to represent the drastically revamped 25th Congressional District that stretches from the edges of Tarrant County to Austin late Tuesday, with slightly more than early votes reported.With four of 224 precincts reported, Williams held a 27 percent lead, followed by Riddle with 16 percent. Cleburne Mayor Justin Hewlett followed with 14 percent of the vote, Dave Garrison had 12.7 percent of the vote and Dianne Costa followed with 11 percent. Former Texas Railroad Commissioner Michael Williams trailed with 6 percent of the vote, with around 14,000 votes reported.Last year's redrawing of congressional district lines flipped the district from a once Democratic-leaning area to a Republican-leaning area - so much so that the incumbent, Democratic Rep. Lloyd Doggett of Austin, switched to nearby District 35 for re-election.The revamped district - now home to the Comanche Peak nuclear power plant near Glen Rose, Fort Hood near Killeen, the University of Texas at Austin and the Texas Capitol - draws its biggest population base, about 240,000 voters, from Austin-area communities. But it also includes 150,000 residents in Johnson County and more than 7,000 in Tarrant County.Here's a look at the early results in other local and area congressional races, according to unofficial results posted on the Texas Secretary of State's website.District 6Longtime Republican U.S. Rep.
