Congressman Ron Paul is leading by a significant margin in Iowa, according to preliminary results of a new TeleResearch poll.

Revolution PAC, the Super PAC formed to support presidential candidate Ron Paul, has received early data from the commissioned Iowa poll. The TeleResearch survey is the first to incorporate disaffected Democrats and Independents who will not vote to reelect Obama and will instead crossover to participate in the Iowa Republican Caucus, as well as likely Republican caucus-goers.

Survey sample size is approximately 2,900, with almost 700 likely Republican caucus-goers. Indiana’s TeleResearch Corp., which has been polling voters for more than 18 years, reports that the margin of error is less than 3%.

Factoring in both Republican caucus-goers and disaffected Democrats and Independents who’ve indicated that they will participate in the Iowa Republican Caucus, Ron Paul leads at 25%, with an approximate 4-point advantage over Newt Gingrich and Herman Cain.

Factoring in only Republicans voters, Ron Paul is in a three-way dead heat for the lead, with Paul and Cain tied and Gingrich trailing by 1 point.

The poll also reveals that more than 27% of all respondents – Democrats, Republicans and Independents – stated that an interventionist foreign policy is the greatest threat to long-term peace and national security.
