How did Democrats block Bush energy initiatives?
The Republicans controlled all branches of gov’t.

Woof: Your memory must be very poor.  They filibustered it in the Senate.  Duh.

There are plenty of domestic sources of oil; just let the oil companies drill for it!

The 2003 bill was filibustered with the help of six Republicans. Ten Democrats went with Bush.
The 2005 bill which passed, left out the sticking points of 2003, the MTBE liability waiver and ANWAR drilling.

You got required ethanol use.

It takes 60 votes to get anything out of the Senate, Woofie.

2003 Bill

Thirteen Democrats switched sides and supported the Republican majority in seeking to cut off the filibuster. Most of these were from mid-western farm states, where the ethanol lobby has pushed hard and has even won the support of Senate Minority Leader Tom Daschle. Both Senators from Louisiana (both Democrats) also supported the bill, most likely due to their long-standing support of their state�s oil and gas industries.

Six bold Republicans crossed party lines to support the filibuster, providing the crucial margin that stopped the bill so far. Senator McCain from Arizona was joined by all five Republican Senators from New England.
