Ron Paul’s campaign is trying to entice Iowa college students who live out of state to come back for the caucus and volunteer for his cause by passing out debit cards to pay for their meals, according to ABC News.

Mr. Paul, a Republican who has proven popular among young and Internet-savvy voters, is putting some of the more than $6-million his campaign raised over the past weekend toward his student supporters, who will receive $40 per day, according to the news network’s political blog.

Iowa’s January 3 caucus date falls when most colleges campuses are closed, although some institutions are making plans to accommodate their students who do come back to participate.

Mr. Paul’s campaign is encouraging its student volunteers and supporters to stay in cabins at a campground outside of Des Moines. A spokesman for the campaign told ABC News that paying students’ expenses will be relatively cheap at an estimated $70,000.

Earlier this month, Barack Obama, a Democrat, came under fire from some of his competitors for his aggressive efforts to encourage Iowa college students from other states to return for the caucuses. His campaign distributed fliers across Iowa campuses and he made appeals to students in his speeches.

Iowa law not only permits students to vote in its caucuses but makes it fairly easy for them to do so, by allowing them to register at voting sites on the day the caucuses are held.

However, other Democrats, including the campaign of Hillary Rodham Clinton, attacked him for asking outsiders to try to skew the results in Iowa.
