I didn’t say that we shouldn’t have third Parties, what I said was they don’t win.
Here are the facts, as listed at the end of my earlier post, what makes you think a new third party would perform any different?:
There has been NO ACTUAL success of third parties. Those who argue that the Republican party itself was a successful third party movement, had best read the history of US political parties.
The Whigs and Free-Soilers joined to form the Republican Party, which strongly supported the abolition of slavery.
The Whig party, emerged out of the National Republican Party, and elected two presidents, William Henry Harrison (1840) and Zachary Taylor in (1848). Out of this base, the Free Soilers and the Know-Nothings, the new Republican Party was formed in 1854, and elected Lincoln in 1860.
I think you are limiting your historical perspectives. You are right that the 3rd Parties never win the White House but a number of Governors and congress critters have been elected from 3rd Parties. Their ideas have influenced American Political thinking. I see the 3rd Party as a way to seek reform, well needed reform, to end corruption. 3rd Parties are a means to protest and bring ideas to the table.
