CARSON CITY, Nev. -- Results of the Nevada Republican presidential caucus will be released through Twitter and Google, the first time the social network will play a central role in announcing the outcome of a political presidential contest.

Precinct and county results will be mapped by Google and linked to the Nevada Republican Party website. State GOP officials anticipate 50,000 to 60,000 will participate in the caucuses, which begin at different times according to schedules set up at the county level.

Adam Sharp, Twitter manager of government and politics, said Friday the plan to release the results would "open up access to this real-time information."

Paul denies report he approved newsletters

WASHINGTON -- Republican presidential candidate Ron Paul on Friday flatly denied a Washington Post report that he was deeply involved in the company that produced provocative, racially charged newsletters and that he signed off on articles.

The newsletters from the 1990s have dogged Paul for years, resurfacing as his presidential campaign gained momentum. The Texas congressman has denied writing the inflammatory passages -- the articles included racial, anti-Semitic and anti-gay content -- and said that he didn't read them at the time or for years afterward.

The Post story published Friday said the newsletters were part of a marketing strategy by Paul's company and that three people familiar with his businesses described his involvement with the newsletters.

"It was his newsletter, and it was under his name, so he always got to see the final product," Renae Hathway, a former secretary in Paul's company, told the Post. "He would proof it."

Paul told CNN on Friday: "She's made that story up. ... It's completely false."
