I would also like to see the "Approval Voting" system being implement. It would make sure the politician that most people agree with the most, will get elected. It would also make it a lot easier for a 3rd party candidate to be elected president.
For example, if 45% would vote for Obama (Democrats), 45% would vote for Romney (Republicans), and each of those 2 factions would also vote for Gary Johnson in proportion of 30% each (out of total voters), then it would be Gary Johnson who would win the election, because he would have the support of 60% of the population, rather than 45% for Obama and 45% for Romney.
The reason this result would be more satisfactory for a larger portion of voters, is because more people actually approved of this candidate from both sides, instead of 45% approving Obama and absolutely hating Romney as a president, or 45% approving of Romney and absolutely hating Obama.
The winner would be the candidate that is liked or approved by the largest portion of the population, which leads to higher satisfaction for the voters after the election.
As an added bonus, because it creates more [viable] parties, it makes attack adds less effective: If you have one opponent, causing that opponent to lose a vote is just as good as gaining a vote for yourself. If you have two or more viable opponents then attacks against any individual opponent helps the remainder as much as you. And in that case, better to be positive about yourself than negative about the opposition.
