Part of Al Gore's announcement of his endorsement of Barack Obama is this:

Over the next four years, we are going to face many difficult challenges -- including bringing our troops home from Iraq, fixing our economy, and solving the climate crisis. Barack Obama is clearly the candidate best able to solve these problems and bring change to America.

"Change?"

What change?

No Change in Iraq

There will be no change in the "war on terrorism." McCain And Obama Are No Different On Iraq, and there will be no change from the interventionist, global hegemony-seeking foreign policy of the Bush-Clinton regime.

Zbigniew Brzezinski was the foreign policy adviser for John McCain's presidential campaign in 1999-2000. Brzezinski is one of the most instrumental members of the Council on Foreign Relations and a founding member of the Trilateral Commission. Now Brzezinski is Obama's Adviser. Nothing has changed, nothing will change.

Brzezinski’s unconvincing antiwar posturing

No Change in the Economy

Ron Paul would have brought change to the economy, by ending The Inflation Tax and The Debt Bubble that has already dragged us into a recession, and will eventually lead to an even Greater Depression. This change would come about by abolishing the unconstitutional Federal Reserve.

Both Obama's advisors and McCain's advisors are Keynesians, followers of John Maynard Keynes, who said the government can bring prosperity by manipulating a nation's currency and credit and redistribute a nation's wealth from the People to the government. President Richard Nixon was one of the first in Washington D.C. to admit the decades-old fact that "We are all Keynesians now." President Obama and/or President McCain will carry on Richard Nixon's Keynesian legacy. There will be no change: that you can believe in.

No Change in Climate

Both Obama and McCain believe the mythology of global warming, and even if their plans are completely implemented, and we only drive our cars every third day and only use our refrigerators and air conditioners on the weekends, and a hundred million Americans lose their jobs, and a billion people around the world are permanently consigned to bitter poverty, and another billion of earth's human beings die outright, global temperature will only be affected by decimal fractions of one degree. It's All Cost, No Benefit, and no change: that you can believe in.

From time to time we've been tempted to believe that society has become too complex to be managed by self-rule, that government by an elite group is superior to government for, by, and of the people. Well, if no one among us is capable of governing himself, then who among us has the capacity to govern someone else?
In this present crisis, government is not the solution to our problem; government is the problem.
-- President Ronald Reagan, First Inaugural Address

Neither Obama nor McCain are able to solve problems. The federal  government can only cause problems. Every dollar the government confiscates, whether directly or through the inflation tax, distorts the Free Market, and moves us further from the solution. The only way things will change is if we understand that government is not the Messiah, Washington D.C. is not our Savior, and that politicians are the problem, not the solution.
