Elena Salinas. Joe Biden did not participate in the debate. During the course of the forum Gravel stated that it was wrong that the father of (Pfc. 3rd Squadron, 3rd Armored Cavalry Regiment) Armando Soriano (age 20, of Houston), killed in Iraq (1 Feb 2004, in Haditha), was about to be deported. Along with the other candidates Gravel committed to immigration reform in his first year as president. Gravel then charged that the national immigration issue was in fact a case of scapegoating immigrants for other systemic problems in the US, in education and health care for example. Gravel said he was embarrassed that the US was building a wall on its southern border. Gravel charged that CAFTA and NAFTA were the real causes of many of the problems on both sides of the US borders but confessed that he thought remedying those acts would have to await the enactment of the National Initiative for Democracy and the empowerment of US citizens as legislators. Gravel said that instead he would reach out to Hugo Chávez in Venezuela and to Castro leadership in Cuba as well. Reminded that health problems had forced Gravel into bankruptcy, Gravel was asked how he would apply his personal experience to the problem of health care. Gravel outlined his plan for healthcare vouchers, paid for out of general revenues, to be applied against premiums of up to five private plans and one government plan, each with identical defined benefits, each mandated to allow freedom of choice of provider. All candidates were accorded equal talk times at the Univision forum. A September 11, 2007 Los Angeles Times/Bloomberg poll found that, among registered South Carolina voters who plan to vote in the Democratic primary or usually vote for Democrats, 2% would vote for Gravel "if the presidential primary were held today". Candidates Chris Dodd, Dennis Kucinich, and Bill Richardson each got 1% of respondents to that question. Additionally in the same poll of South Carolina voters, in response to the question, "Regardless of your choice for president, who do you think has the best chance of beating the Republican candidate in November…?" Gravel polled 2%, compared to 1% for Joe Biden and Bill Richardson, and 0% for Chris Dodd and Dennis Kucinich. During mid-September 2007, Yahoo!, in partnership with The Huffington Post, produced a "mashup debate" with Charlie Rose interviewing the candidates. Segments were recorded on September 12,
