I've been writing for the past 10 years how the 2-party system has failed Americans. So, here's some more...
A strong 3rd party will have little effect on positive change because the same thing may happen with that party as has with the other two.
I strongly believe that first we must revise/modify the current laws on campaign financing and legislative perks from wealthy constituents and corporations.
If we could do that immediately, we actually may save the 2-party system from "killing" itself.
Previously, I have discussed one option of eliminating the two parties and "merging" them into one. After all, in many ways they are not THAT different from each other. In fact, doing this may be more beneficial than it was when Chrysler merged with Daimpler/Mercedes because the two corporations had so little in common, e.g., one was American while one was German. Relating to the cars each made, that just wasn't a good deal. Further proof of that is recently Daimler-Mercedes sold Chrysler after large losses for each company.
So, what are the differences of the two parties?
Democrats = tax and spend
Republicans = tax cuts and spend
While that may be an over-simplification, "the shoe fits" for each.
Once we have "merged" the parties and after the initial "in-fighting" that is sure to occur, perhaps then the members will settle-down and work together to create reality-based positive changes.
One of the options we need to create to make some worthwhile changes to our current system is to pass a law that mandates U.S. citizens MUST vote and then provide various penalties for not voting, e.g., freeze bank accounts, implement a monetary penalty, suspend a driver's license, etc.
At least that would force us to improve voting percentages, which I believe then would improve outcomes.
After that, we need to improve on how we select those who comprise the electoral college. Currently, that's a disgrace for the most part. We need to base selection on life experience, no favoritism or special interest connections, etc.
Then we need to REALLY improve how we vote, a.k.a., ensuring voter and voting machine integrity. Currently, Diebold is the one of the largest manufacturers of voting machines and yet it also contributes to the campaigns of George W. Bush! "Conflict of interest" anyone????
That in turn leads us to eliminating "conflicts of interest" among our leaders/elected officials.
Case in point: Look at VP Dick Cheney. You don't think there still is a conflict of interest there that is affecting our democratic policies and laws? He was supposed to give up his ties to Halliburton upon becoming VP; however, he still has stock options and other perks that you can "bet the farm" influence his decision-making.
All the above are just a few issues I believe in.
