Talking Points Memo, a political site that has been around since 2000 but only became a force outside Washington in the last few years, plans to expand its reporting staff to 15 people. In 2008, it had only one full-time reporter and an intern assigned to the campaign. According to the site’s founder, editor and publisher, Josh Marshall, the goal is to create a bigger name for the blog by competing with newcomers like Politico and more traditional news outlets like The Washington Post and The New York Times.

In the 2004 campaign, Mr. Marshall said, “We were sort of a player.” By 2008, the site had become “a small but significant player,” he said.

But now, he said with a sense of pride, “We’ve already got reporters assigned to different campaigns.”

“It’s an entirely different game for us.”

RealClearPolitics plans to more than double the number of reporters covering the 2012 campaign to at least six and possibly eight, according to John McIntyre, the Web site’s chief executive and co-founder.
