Gov. Martin O'Malley

Gov. Martin O'Malley (May 29, 2014)

Gov. Martin O'Malley, who is considering a run for president in 2016, will return to Iowa next month to give the keynote address at the state's Democratic party convention.

The June 21 trip to the first-in-the-nation caucus state is part of a more intense round of travel O'Malley has been engaged in since the legislative session ended this spring. The governor is also set to visit New Hampshire again next month.

O'Malley last visited Iowa in 2012. Democrats are defending an open Senate seat in Iowa this year after Sen. Tom Harkin decided not to seek reelection.

"As we head into a vital election year, Governor O'Malley will help support our candidates up and down the ticket as Iowa Democrats work together to change course for our state's future," Iowa Democratic Party Chair Scott Brennan said in a statement. 

O'Malley, who is term-limited in Maryland, has clearly been preparing for the possibility of a presidential campaign for months, despite polls that indicate former Secretary of State Hillary Clinton would dominate the Democratic field if she decides to run. As part of that effort, O'Malley has been building a network of campaign donors and travelling to early primary states.
