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...

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.
