John Delaney, a Democratic candidate in Maryland’s 6th District, is calling for 12-year term limits for members of Congress, an extended “cooling off” period before lawmakers can become lobbyists and a plan to allow some illegal immigrants to stay in the country, his campaign said Tuesday.

The proposals were included in a broader platform document posted on the Potomac financier’s campaign website. Though many of the ideas are short on specifics, the document represents a shift in focus toward issues after weeks in which the two most active candidates in the Democratic primary have lobbed attacks at one another.

Delaney is running against State Sen. Rob Garagiola and three other Democrats for the party’s nomination. The district is currently held by Republican Rep. Roscoe G. Bartlett, a 10-term lawmaker who is seeking reelection in what political analysts predict will be among the most competitive House races in the country. The primary is April 3.

“In these economically tough times, voters deserve solutions, not spin,” Delaney said in a statement.

Most of the ideas hue closely to policies proposed by President Barack Obama and Democratic congressional leaders, including some that have failed to gain momentum. For instance, Delaney said he would support legislation to allow illegal immigrants who were brought to the country as children and who spend two years in the military or college a chance to stay in the U.S. That proposal, known as the federal DREAM Act, died in the Senate in 2010.

And as is often the case in primary elections, it’s not clear how much difference there will be between the Democratic candidates on the issues. Another Democratic contender, Jefferson physician Milad Pooran, previously posted a platform on his website that includes many of the same policy positions as Delaney, including more spending on infrastructure projects to spur job creation and allowing Bush-era income tax cuts for the wealthy to expire at year's end.

But Delaney is the first of the major Democratic candidates to call for term limits, an idea that was an initially supported by Bartlett but that he later abandoned. Delaney is also suggesting that Congress should extend the “cooling off” period for House lawmakers who want to become lobbyists to five years from one year.

“Term limits can increase electoral competition and serve as a check against entrenched career politicians and special interests,” Delaney’s campaign website reads.
