SALES of Kelly Clarkson's latest album "Stronger" nearly doubled in one day following her endorsement of Ron Paul in the Republican presidential primary.

A section of Clarkson's fans used social networking sites Thursday to blast the singer for supporting Paul in light of racially derogatory comments contained in newsletters he published around 20 years ago.

But despite the online backlash, sales of her latest release have soared by 192 percent on Amazon.com in the wake of the criticism.

"Stronger," her fifth studio album, shot from 41 to 14 on the website's "Movers & Shakers in Music" list in 24 hours, according to the Gossip Cop website.

Clarkson, 29, tried to quell Thursday's controversy by tweeting her support for equal rights, but she stood by the Texas congressman "because he believes in less government."

The "American Idol" season one winner ruefully confessed that she should have heeded the advice of her dad, "who said never to share my beliefs on religion & politics."

Despite the surge in online sales, however, some fans told FOXNews.com their days as admirers of the Dallas native were over.

"I used to like Kelly Clarkson. But I can't like anyone who is either ignorant enough or arrogant enough to endorse a candidate like Ron Paul," Spafford Freeman said.

"I have listened to 'Since You've Been Gone' for the last time."
