(CNN) - The crowded GOP presidential field added one more candidate Thursday.
Former Louisiana Gov. Buddy Roemer officially declared his candidacy at the Hanover Inn at Dartmouth College in New Hampshire, becoming the 11th Republican candidate to jump into the race.
"You don't want to miss this campaign," said Roemer. "It will be something else."
Roemer blasted President Barack Obama and the other candidates, saying they're ignoring two issues he sees as major problems: "unfair trade" and special interest campaign contributions.
Pledging to refuse PAC money and only accepting donations of $100 or less, Roemer has so far raised nearly $96,000, with nearly $41,000 raised in the second quarter.
"I ask the 98 percent of Americans who never give to a presidential candidate to stand with me," Roemer said.
Roemer served four terms as a Democratic congressman from Louisiana then became governor of the state in 1988. He made headlines when switching affiliation to the GOP in his third year as governor and lost re-election to a second term. In the private sector, the Harvard graduate worked as the CEO of Business First Bank after leaving office.
