Such PACs are often used by politicians to contribute money to candidates around the country and strengthen relationships that could be helpful down the road.

O’Malley’s “O’ Say Can You See” PAC will also be a vehicle for the governor to raise money for two high-profile ballot measures this year in Maryland — on same-sex marriage and immigrant tuition rates — spokesman Rick Abbruzzese said. O’Malley will draw on the PAC to continue to campaign for President Obama as well, he said.

O’Malley’s national profile has risen considerably during his two years as chairman of the Democratic Governors Association. He is now routinely mentioned as a potential Democratic candidate for president in 2016.

The new PAC, which was first reported by Roll Call, will give O’Malley “the resources and ability to continue to participate in the national conversation” after his second term as DGA chairman ends in December, Abbruzzese said.

Martin F. Cadogan, O’Malley’s longtime campaign treasurer, is listed as the treasurer of the federal PAC in a filing this week with the Federal Election Commission. O’Malley’s existing fundraising team will also raise money for O’ Say Can You See, Abbruzzese said.

The PAC’s name comes from the first line of “The Star-Spangled Banner,” the lyrics for which were penned outside Baltimore by Francis Scott Key two years into the War of 1812.

O’Malley, a former mayor of Baltimore, is an avid student of the war and has participated in commemorations this year marking its 200th anniversary.
