In 1776, George Washington needed the full support and backing of the people to get the job done. And they sacrificed their wealth, and their very lives, to obtain a successful result.
Those of us not willing to take the same level of personal responsibility, and make (if necessary) the same sacrifices, have no right to blame leaders, politicians or political parties for our own failures.
There's a reason we only have two political parties that matter, and the reason is mathematical: In a winner-take-all electoral system, there can only be two parties of any consequence. And in the 235 years of our history, there is only one instance where a new party replaced one of those two (the Republicans replaced the Whigs.) The important word there is replaced. There will still just two parties of any consequence.
What has happened much more frequently is for one or the other party to be taken over from the inside by activists with a new philosophy, vision and agenda. That strategy is much more likely to succeed than attempting to replace one of the parties with a new one.
Don't sit there at your computer bitching. Go do what needs to be done.
Unfortunately, after Perot’s surprising success, the two parties conspired together, and made sure that 3rd party success is virtually impossible. It’s nice to talk about replacing the GOP with the Limited Government Party (or whatever), but the actual practice is pretty difficult, especially when at least 25% of the GOP faithful simply cannot allow themselves to change that letter in the boxes they check every Election Day.
