"Our country is at a critical juncture," Spratt said to about 30 supporters in Hartsville.
He listed issues ranging from Social Security, health care and the budget deficit to war and terrorism as priorities for the next term of Congress.
"I have the skills and experience to make a contribution," he said.
Spratt, who was first elected to Congress in 1982, is the ranking Democrat on the House Budget Committee.
He said if Democrats win a majority of U.S. House seats in the 2006 general election, he would be chairman of that committee.
"I feel that chances are good that (Democrats) will take back Congress," Spratt said.
He said even though the 5th District stretches from Rock Hill to the Midlands, he has done his best to make sure the Pee Dee has been served.
"I've tried to make you feel that you are important to me," he said. "My constituent services are second to none. I have helped hundreds (of people) get their fair share from the federal government."
Aside from mentioning his local involvement, Spratt touched on national politics.
He decried a $423 billion deficit attached to the national budget and criticized President Bush for it.
"When (Bush) took over he had a $236 billion surplus," Spratt said.
Spratt said he was one of four congressmen who helped craft a budget that resulted in the surplus. He said he wants to see the budget balanced again and will work toward that if he is sent back to Washington.
Spratt also said he has worked to help bring the state $91 million in federal funds for the proposed Interstate 73, which is projected to run through several Pee Dee counties.
He said he has to helped working families get health insurance, too.
Darlington Mayor Tony Watkins, sporting a red-and-white Spratt for Congress lapel sticker, was on hand.
"We need John Spratt in Congress," Watkins said. "He has helped in Darlington, and we will need his help and seniority in the future."
Ed Hursey of Hartsville said he has much enthusiasm for Spratt.
"He's one of the finest men in Congress. He has high morals and ethics. He is real smart. I urge people to vote for him," Hursey said.
Spratt has no opposition in the June 13 Democratic Party primary.
Rep. Ralph Norman, R-Rock Hill, is the lone Republican running against Spratt.
GOP candidate Park Gillespie withdrew his bid to challenge Norman in the party's primary earlier in the month.
