Does America need a Parliamentary system?

"Although parliamentary systems can thus seem less stable than presidential ones, they are held together by the fact that their heads of state provide an element of stability not found in presidential systems. Since the head of government is the head of state in a presidential system, he or she cannot be a neutral political player. For example, President Obama cannot be a neutral political figure in the same way Queen Elizabeth II is. He is an elected figure from a major political party, and as such, he campaigns for his party. This is inherently polarizing."

"Institutional change in the United States is wishful thinking. Theoretically, however, without constitutional changes, some moves can be made in that direction. For example, the speaker of the House could became a prime minister of sorts, elected by the majority of the House, and take executive decisions if the president is willing to serve as a sort of ceremonial rubber stamp. This is, of course, unlikely. But if gridlock continues and the United States continues to have elections like the present one, in a few decades, a strong case can be made for major constitutional restructuring."
