Political Parties out of balance

The trouble with U.S. politics right now is that the parties are off balance. They are faltering.
The Republican Party was weakened in the early 1990s. This left a power vacuum that the Religious Conservatives (who are normally fundamentalists) and pseudo-Libertarians (gun nuts) filled in the mid-1990s. These groups don’t care about traditional positions of the Republican Party. They have used it to accomplish their own ends. Many of the actions taken by the Republican Party in recent years are in direct conflict with the party’s traditions. (Side note, anyone fundamentalist who believes that second coming of Christ is going to replace the U.S. government shouldn’t be in politics in the first place, since they may misinterpret the bible and decide now is a good time for Armageddon; not to mention other basic problems that I may get into at some other time. I mention this because of the harsh religious tone of the Republican Party right now.)
The Democratic Party was the status quo for much of the 20th Century. They seem lost now that the dynamics of the Republican Party has changed. They are now weakened, similar to the Republican Party of the early 1990’s. Except in the Democrat case, there doesn’t seem to be groups ready to fill their power void. I don’t know if this is a good thing or not. One the one hand, their traditional positions are being held on to. On the other hand, without some sort of fresh blood take over, they will flounder for many years to come.
I hope the Democratic Party can get organized soon. I hope that the Republic Party moves away from realm of religious ideologies. I’m a centralist (not a moderate). I am happiest when the two parties are in balance. When there is a balance, the government is less likely to tell me or any citizen how to live our lives.
