Women shouldn't be allowed to vote or hold positions of power for one simple reason. Most women make decisions based on EMOTIONS instead of FACT.
As we are now seeing, a government heavily influenced by women will be overrun with bleeding heart social programs (expanding welfare state) even in the wake of much bigger problems (faltering economy).
The FACT is that we don't have the money for these social programs. However, since women have been allowed in to the political world, the EMOTIONAL response allowing these social programs has been HUGE!
