A TRUE DEMOCRACY?

Why do we here in the U.S call our system a true democracy, especially one that other countries around the world would be better off imitating, when we have only two parties which represent the plethora of citizens living in this country? Israel has what is called a democracy, although the power that is wielded sometimes borders on the extreme, nevertheless, they have twenty mainstream parties representing the citizens that have all kinds of different interests, not just two mainstream ideas. Which brings up another question- are the Demacrats and the Republicans truly that different in ideology from one another? True, the Democrats may be looked upon as more liberal and the Republicans as more conservative, unless you look at the middle of both parties-there the ideologies are almost exactly the same. If you move to the left in the Demacratic Party, surely the ideas become more liberal, but the same is true for the Republican Party. If you move to the right in either party, the conservative elements and ideas are more prominent.
Why is it so hard for a country as large as the U.S. to contemplate the idea of more than two parties? Even the so called Independent Party is looked down on by mainstream politics as being outside the bastion of true political ideals. Isn't it time for there to be at least the possiblity of more than two parties, which when looked at closely resemble each other almost identically in thought and action?
What if there were a party which represented each of the following: the ultra-religious, the working man, the rich and elitist, the poor on welfare, or does one size fit all, as the two parties that exist would like us to believe? Is there enough difference between the Republicans and the Democrats and the different levels of each party to cover all the multitude of people who hold the right to vote in this country? Maybe, just maybe, it is time for more of a choice than what we have at present before us in the form of politics in this great country.
