Tap the Oil Reserve? Why?

Noted here:

....for all the rhetoric about flat-earthers who believe in strange things like supply and demand, Obama himself knows that increasing oil supply does matter. Why? Because he is pondering again tapping the strategic oil reserve, while Democratic senators keep reminding us that the U.S. is begging the Saudis to increase their own production. So why would increased oil from a reserve or from Saudi Arabia matter in a way that increased domestic production heretofore has not? --Cold Fury quoting VDHanson/Corner

Irony abounds, and Obozo is its bitch.
