OpenSecrets.org is a legit site and they have nothing to gain by spreading a false story about Ron Paul. If it’s true that Ron Paul presidential campaign tried to buy endorsements in the Iowa Caucuses, they may damage his son more than anything. I don’t know why Paul would have to buy endorsements as they mean little anyway. According to Open Secrets:
The Ron Paul presidential campaign may have been involved with negotiations to offer financial compensation to an Iowa state senator in exchange for his endorsement and support in the 2012 Iowa caucuses, according to emails obtained by OpenSecrets.org.
The negotiations appear to have involved several top Ron Paul 2012 officials, including Jesse Benton, pictured with Ron Paul at right, who was the campaign’s political director. Benton is married to Ron Paul’s granddaughter and is currently managing Senate Minority Leader Mitch McConnell’s 2014 campaign.
In an Oct. 29, 2011 email, a representative of Iowa state Sen. Kent Sorenson, a Republican, asks the Paul campaign to provide Sorenson with $8,000 per month in salary for him, $5,000 per month in salary for a Sorenson ally, as well as $100,000 in contributions for a newly created PAC that Sorenson planned to use to support conservative candidates for Iowa state office.
