WASHINGTON (CNN) -- Sen. Mel Martinez, R-Florida, praised the GOP presidential field Monday, and predicted his party will not have difficulty raising money for the 2008 election cycle.

"I really frankly like our field," said Martinez, who also serves as the general chairman of the Republican National Committee. "I think we're going to be fine and I think the support will be there."

Martinez also credited the "excitement" surrounding Illinois Sen. Barack Obama, D-Illinois, as one of the reasons why the leading Democratic presidential candidates collectively out-raised their Republican counterparts in the first quarter of 2007.

"I think that there's been a lot of excitement about someone like Barack Obama -- I know him in the Senate, I serve with him -- and I think that that all has generated an awful lot of excitement," he said.
