Flush with cash after another record fund-raising event, the campaign of Ron Paul said Monday that it was hiring more staff members, expanding its ground operations in early primary states, planning more advertising and looking ahead to competing in the contests on Feb. 5.

Supporters of the campaign broke a record on Sunday when they raised just over $6 million in an Internet campaign for Mr. Paul, a 10-term Republican congressman from Texas whose antiwar, libertarian message has caught on with an enthusiastic and generous segment of the electorate. It raised an additional $360,000 on Monday.

The donations eclipsed a previous one-day fund-raising record of $5.7 million, set by Senator John Kerry in 2004 after he accepted the Democratic nomination for president. Mr. Paul’s previous single-day fund-raising high was $4.2 million on Nov. 5, raised in a campaign set up by supporters.

The latest fund-raiser was timed to the 234th anniversary of the Boston Tea Party, to underscore Mr. Paul’s message of changing course in America. His agenda includes pulling out of Iraq, doing away with the federal income tax and eliminating bureaucracies like the federal Department of Education.
