Respondents were asked: Q18. If the 2012 general election for U.S. Senator from Texas were held today, would you vote for the Republican Ted Cruz, the Democrat Paul Sadler, the Libertarian John Jay Myers, the Green Party candidate David Collins, someone else, or haven't you thought enough about it to have an opinion?
If they initially answered that they didn't know, they were then asked a follow-up question: "If you had to make a choice, who would you choose?" Responses to the follow-up questions were folded into the results found above.
"Likely Voters" were defined as those who indicated that they were either "Extremely" or "Somewhat" interested in politics in Q2 AND either voted in "Every" or "Almost every" election in Q3.
