Washington: Real estate Business tycoon- turned politician Donald Trump is leading among the Republican presidential candidates, with his nearest rival Ted Cruz trailing behind by 14%, a latest opinion poll said.
Trump, 69, has support of 34% of the likely Republican primary voters against 20% for Cruz, 45.
Florida Senator Marco Rubio is the only other Republican presidential aspirant to get pass the double-digit support with 11%, Fox News said.
Ben Carson came fourth with 8 %. Trump was also leading the poll done earlier this month with 35% support, with Cruz at 20%.
With Cruz being his nearest rival at the national level, Trump has launched a scathing attack on the Texas Senator over Twitter.
"Is Cruz honest? He is in bed with Wall Street and is funded by Goldman Sachs/Citi, low-interest loans. No legal disclosure and never sold off assets," Trump alleged.
In another tweet, he questioned the citizenship of Cruz.
"Cruz did not renounce his Canadian citizenship as a US Senator - only when he started to run for POTUS (President of the US). He could be Canadian Prime Minister," Trump said.
Earlier in the day, Trump unveiled his latest campaign ad aimed at Cruz and focused on illegal immigration.
"Ted Cruz is a total hypocrite and, until recently, a Canadian citizen who may not even have a legal right to run for President," Trump alleged.
"He didn't disclose loans, pretending he's Robin Hood, when he's just another all talk, no action politician. Had I not brought up the subject of illegal immigration, an issue which Cruz is very weak on, nobody would even be talking about it. I will build a great wall, and Mexico will pay for it," Trump said.
