DES MOINES, Iowa (AP) — Once he announces his presidential decision, Martin O'Malley will waste no time in getting himself to Iowa.

O'Malley will campaign in the leadoff caucus state on May 30, the same day he makes an announcement in Baltimore about whether he will seek the Democratic presidential nomination. A Democrat with knowledge of O'Malley's travel plans, who spoke on condition of anonymity so as not to pre-empt the formal announcement, said O'Malley would appear in Davenport in the afternoon and Des Moines at night.

If he runs for the nomination, as his travel plans strongly suggest he will, O'Malley will join former Secretary of State Hillary Rodham Clinton and Vermont Sen. Bernie Sanders as the major candidates in the race for the Democratic nomination.

The former Maryland governor has made several visits to the early caucus state this year, has two paid staffers on the ground and plans to add more. He also invested heavily in Iowa last year, making four trips to the state and putting 14 staffers to work on state campaigns.

During a visit earlier this year, O'Malley said Iowa Democrats needed to get to know him. He said that at a certain point, "the race quickly narrows between the once inevitable front-runner and the new and unknown candidate who emerges to offer a more compelling alternative."
