WASHINGTON (CNN) – During the 2008 presidential campaign, analysts noted that then-Sen. Barack Obama ran a relatively tight ship - complete with a near lock-step message strategy and a loyal political team.
But since Obama has become president, some say his administration is failing to reflect the tight-knit campaign that helped lead the Illinois Democrat to victory.
One reason: Size matters.
That is, the vast size of the federal government, bureaucratic red tape and the scale of his top advisers' egos, according to an influential political observer.
"When you're running the country, it's a whole different ball game," said Stuart Rothenberg of the Rothenberg Political Report. "Not only is the number of people exponentially larger in terms of the number of people involved, but you have bigger personalities; you have egos; you have people of accomplishment who are accustomed to speaking their mind."
A second reason: Frustration.
Several Democratic Party members are frustrated by the president's lack of progress on big issues. Liberal Democrats are frustrated for his not forcefully pushing the government-sponsored public option idea for health care reform.
Activists also are worried about the president's inaction on repealing the military's "don't ask, don't tell' policy, which effectively bars openly gay people from serving in the military.
But a former top Obama campaign aide said gay Americans have every right to be impatient and continue to pressure the president and Congress.
