Republican presidential nominee Donald Trump has one of his slimmest leads yet over Democratic rival Hillary Clinton in Texas, 41 percent to 38 percent, according to a new poll among registered voters. Trump’s support falls within the survey’s margin of error, which is plus- or minus 3 percent, meaning the race is a statistical dead heat.

Released Tuesday by the University of Houston's Hobby School of Public Affairs, the poll also found that 16 percent of respondents were undecided or refused to answer. Four percent chose Libertarian Party candidate Gary Johnson and 1 percent selected Green Party nominee Jill Stein.
