Why won't liberals in congress allow a vote on drilling?

Drilling would bring down the price of oil today!!! The futures market by definition is determined by factors in the future. So if speculators see a jump in supply years from now, they will bid down the price of oil. Liberals fail to understand that the same problems that got us into this mess can be taken care of by drilling(speculation and supply-demand). If you think the same country that put a man on the moon in the vicinity of 10 years can't get oil out of the ground in less than you are kidding yourself. And even if what your saying was true, no effect in 10 years, well how the heck will wind power and solar power have an effect in less than that. When was the last time you drove your car on wind. The truth is we had this debate 10 years ago with Clinton and you liberals used the same excuses then, but had we drilled then we would be seeing the benefits today. I say we should learn from history. Now drilling isn't the only solution. We must conserve and must invest in renewable but drilling is the start.
