http://en.wikipedia.org/wiki/Leo_StraussStrauss was a complex charater, called by some an "unconvinced atheist", i.e. he opposed Atheistism not because he believed in God, but that he though religion was useful for the ruling elite of a society. As one commentator said of Strauss's philosophy:
"perpetual deception of the citizens by those in power is critical because they need to be led, and they need strong rulers to tell them what's good for them."
In many ways that is the GOP motto to this day, use the fundamentalists to get in power and stay in power, but ignore them when it comes to what they really want. One of the reason the Democrats won in 2006 and 2008 was that the fundamentalists had been turned off by the lack of passage of what they considered most important when the GOP controlled the House, the Senate and the Presidency. The fundamentalists basically sat out those elections.
With the results of 2006 sunk in, the Corporate Right wing tried to get the fundamentalists back into the ball game, but they continue to sit out the election in 2008. Thus, to get around the problem that the fundamentalists could NO longer be counted as votes for the GOP, the Corporate elite founded the "Tea Party" movement, to try to get these same people out to vote. The "Tea Party" is an attempt by the Corporate elite to get back in control of the Presidency and the Congress by trying to get the same people who backed the fundamentalists agenda (And turned off voting when they did not get that agenda even addressed under Bush) back into the voting booth without having to actual promise them anything. Some of the old fundamentalists leaders are leaders of the "Tea Party" movement, but much of the lower level fundamentalists leaders are not (They are like their fellow fundamentalists waiting to support a candidate that will pass laws that the fundamentalists want, including some social reforms).
Sorry, this large increase in the number of atheist reflect the increase number of follows of Leo Strauss within the GOP. It is NOT a good thing for the Country and clearly not a good thing for Congress.
