"Only once in my lifetime has one of the major political parties split in two"
Do you believe that this is a bad thing? I don't. I believe that the more people stand up for their beliefs, the better off the country will be. The American people, as a whole, have been far too complacent over the last several decades, not participating in the political process for far too long. That is what has led to the "take over" of our political system by the "extremes".
OK, it has happened during our lifetime. Why is that important? Man is a rather short lived animal. Generally speaking Man sees everything in those terms. If something is during his lifetime that is how it should remain. We see this in politics, we see it in the "global warming" argument. The statement that
"it has never happened in my lifetime" is a common "argument when people don't understand, like or dislike whatever they are talking about.
We are looking at processes that have been going on for hundreds of years. It was, historically speaking, not very long ago that the Republican party was formed. It was a split off from the Whigs, in 1854, they were the anti-slavery "branch".
The process is slow, and despite what "news outlets" say, takes place over many lifetimes. Much of what has led to the "Tea Party" started long before WWII ever started. A lot of what may end up being good, or bad, since Obama has taken over, will not be seen until my granddaughter's children are having their own children.
The "political process" did not end in 1854, there will be other parties, some may take hold, some may not. There will come a time, when the same type of "split" takes place in the Democrat party. Nothing is static. It is like slow, steady moving lava. It will always move, slowly.
