Roslin is not the equivalent of an American President. The America President is the leader of the armed forces. It is not the case with the 12 colonies.
Actually, the show has gone out of it's way to show that the government of the Twelve Colonies is a direct parallel to the modern United States of America, he's even said it himself:
1. An elected President and Vice President as the supreme executive (Instead of a President/Prime Minister, Governor General/Prime Minister, Monarch/Prime Minister combination like most other modern human governments).
2. A series of Cabinet Secretaries as a chain of succession in the event of an emergency (Instead of Ministers as the title, again, fairly unusual government title).
3. The shot of Roslin's swearing in aboard Colonial One was an
intentional reference to Lyndon Baines Johnson's swearing in aboard Air Force One after the Kennedy assassination.
4. The "Lest We Forget" picture in Roslin's office is also an intentional reference to the famous picture of firefighters raising the flag at Ground Zero after the 9/11 attacks.
5. The radio callsign of the executive transport is Colonial One, a blatant reference to the Air Force One/Marine One/Navy One/Army One/Coast Guard One/Executive One radio call signs.
6. They wear the exact same clothes as modern day north Americans, their cities even have the same street signs.
7. They drive the exact same vehicles (humvees, deuce-and-a-half trucks) in their military.
8. The series creator has the Quorum of Twelve is intentionally an analogy to the U.S. Senate, with some elements of the UN Security Council, and that there was a much larger second house of legislature which is currently inactive, as well as an independent Judiciary that has yet to be reconstituted (from his online comments).

BSG Creator Ronald D. Moore Official Podcast Commentary said:
Unlike the original series, I didn't want the political leadership of the rag-tag fleet to be strawmen for Adama to knock down over and over again... I didn't like the notion that what you really need is just a good smart, military man who can control and run everything. I liked playing the natural tension between the civilian and the military authority in this situation. I wanted to explore what it really meant to be a democracy in a republican form of government. And it says something interesting about the Colonial society, that they do value and treasure and place great emphasis on the fact that their government is still with them.
The entire Laura Roslin plotline throughout the series is really a tribute to the fact that how strongly these people believe in their system of government, how fundamental the notions of democracy and representation and the vote and equal rights -- the sort of things that in this country, the United States, are also built into our culture. We have the fundamental belief in the Constitution and the Bill of Rights... I wanted the rag-tag fleet to mirror our society in that way.
The creator has said outright that the show is meant to be viewed through the lens of contemporary American civil values and legal/cultural traditions (except for the Colonial religion), and that in the long run, even the series creator intends to depict Adama/Tigh as being in the wrong.
It was never said that Adama had absolute control of the military, or that he was not ultimately accountable to Roslin. In the miniseries, immediately after the attacks, Roslin agreed to
de facto share power with Adama, with Adama dealing with military affairs and Roslin dealing with civil affairs. This was also when she was getting used to the Presidency, and wasn't ready for the power vested in her. Roslin, being unskilled in strategy and more a career bureaucrat knew that she should't be micromanaging military affairs, and wasn't particularly interested in the details of the war. However, after having several months to get used to the office and come to terms with her responsibilities, in a situation where the fate of the entire fleet was at stake: the chance to retrieve the relic which could tell the fleet the location of Earth, she exercised Executive authority and countermanded a military order, which she hadn't done before but was still within her legal authority.
