Democratic presidential nominee Hillary Clinton is narrowing in on her Republican rival Donald Trump's lead in Texas which has dropped from double digits to under 5 per cent in the last two weeks, according to a new poll.


According to Washington Post survey 'Monkey poll' Trump is ahead of Clinton by only 2 points in the lone star state. In a University of Houston poll, the Republican presidential nominee is leading by 3 points, whereas the survey 'USA/Texas Tenga poll' showed him ahead by 4 points.


Trump, 70, is still winning Texas, but his advantage has dropped precipitously from double digits to under 5 per cent in the last two weeks, the survey said.


Released yesterday by the University of Houston's Hobby School of Public Affairs, the poll also found that 16 per cent of respondents were undecided or refused to answer. Four per cent chose Libertarian Party candidate Gary Johnson and 1 per cent selected Green Party nominee Jill Stein. Republican presidential candidates have won Texas by no less than 11 percentage points since 2000, according to a memo accompanying the poll results.


Democrats last won Texas in a presidential race in 1976.
