WASHINGTON (CNN) -- In the latest sign that New York Gov. George Pataki is seriously considering a run for the White House, the Republican's political action committee is set to open up offices in Iowa and New Hampshire in the coming days.

Pataki's 21st Century Freedom PAC will open its Urbandale, Iowa, office on Friday and a Manchester, New Hampshire, office on Monday. At Friday's event, Pataki will announce the addition of several Iowa Republicans to his leadership team.

Alicia Preston, a spokeswoman for the PAC, dismissed speculation that Pataki is ramping up for 2008. "The opening of these offices reinforces the governor's dedication to help Republican candidates win in November," she said.

Still, Pataki has been making the rounds of the influential, early presidential proving grounds of Iowa, New Hampshire and South Carolina. And his PAC employs four paid staffers in the Hawkeye State and one full time staffer in the Granite State as well as the influential New Hampshire GOP consulting firm Meridian Communications.
