Why didn't the four candidates who were once in the Congress at that time propose the laws they later argued were so vital to the country?
Referring to past presidential candidtes Hillary Clinton, McCain, Obama and Paul.
This question refers to the last election. There could be many reasons for this, but the most important reason is that the president is supposed to be the one to come up with and suggest ideas that will truly change the country. One member of Congress does not really have this power.
Of course, any of these people could have introduced legislation on any topic when they were in Congress. However, none of them would have had the power or the visibility for those proposals to have any chance of passing. If, for example, Sen. Obama (a first term Senator) had proposed a comprehensive health care plan, it never would have had a chance. He was not famous and did not have much power.
When people run for president, they have to outline their vision for what they would do once they got the power and visibility that comes with being the president. While they are still in Congress, they have very little chance to get any truly sweeping reforms passed.
