Rick Noriega is running against incumbent John Cornyn for Senator from Texas. While Cornyn is pretty horrid, Noriega is even worse. From his about page (ricknoriega.org/about):

The most significant accomplishment of Rick's second session in 2001 was passage of House Bill 1403.This was an historic bill, making Texas the first state in the country to provide in-state tuition rates and financial assistance for certain immigrant children; today, thousands of them are attending college.

...For his courage in authoring HB 1403 and his leadership in shepherding the bill through the legislative process, Rick received numerous awards including one from the Texas Association of Bilingual Educators, Texas LULAC. He was also selected by the Texas Association of Chicanos in Higher Education (TACHE) and Hispanic Journal as "2001 Legislator of the Year." The government of Mexico honored Rick with the Ohtli Award in 2002, presented to U.S. citizens of Mexican descent who have distinguished themselves in public service.

As described here many times, bills like 1403 have the impact of taking college educations from U.S. citizens in order to give them to foreign citizens who are here illegally. Noriega is on their side, not ours. And, the Ohtli award is presented to U.S. officials who help that country push their agenda inside our country.
