In first 100 days, Obama flips Bush Admin's policies.

Sure, it's the economy, stupid. But Obama's first 100 days get an A for sticking to his campaign promises and overturning some nasty Bush-era stuff. Here's a good summary from ABC News. Some excerpts:

Marijuana:

Signaling a drastic shift in the Bush administration's policies on drugs, Obama's appointed Attorney General, Eric Holder, said federal agents will relax their enforcement of marijuana laws and go after only those distributors who violate both state and federal law.

Gay Rights:

On March 18, the Obama administration formally endorsed a United Nations statement urging world leaders to decriminalize homosexuality, a declaration that less than three months ago Bush refused to sign.

More changes to Bush's rules on homosexuality are likely to come in the next four years. Obama promised in his campaign to overturn the "Don't Ask, Don't Tell" policy that stemmed from the 1993 law that forbade homosexuals from serving in the U.S. military.

Stem Cell Research:

In his latest rollback of Bush administration policies, President Obama signed an executive order Monday lifting the 7½-year ban on federal funding for embryonic stem cell research and a memorandum covering all scientific research. In a less-than-subtle criticism of Bush's ban, Obama said, "In recent years, when it comes to stem cell research, rather than furthering discovery, our government has forced what I believe is a false choice between sound science and moral values. In this case, I believe the two are not inconsistent," the president added before signing the order.

Global Gag Rule:

The debate on whether U.S. government should fund international family planning groups that provide abortions or related services has been brewing for decades.

Obama overturned the policy on Jan. 23, just days after he took the oath of office. "For the past eight years, [the restrictions] have undermined efforts to promote safe and effective voluntary family planning in developing countries," Obama said in a statement.

Patients Rights:

Breaking with Bush on health care, Obama wants to give more power back to the patients on whether health care providers should provide controversial services. The administration revoked the Bush-era "Provider Conscience" rule that created more regulations to prevent those who refuse to hire doctors and nurses opposed to abortion rights from receiving federal funds. The move was applauded by abortion rights advocacy groups, who say the limits restricted patients' rights.

Guantanamo:

In his first major step in office, Obama signed an executive order closing down the detainee center at the Guantanamo Bay military facility within a year, and established new guidelines on interrogation methods and the treatment of detainees. In another order signed on the same day, Obama mandated all U.S. interrogators in all agencies to adhere to rules in the Army Field Manual, and the president also called for the shut down of CIA detention centers around the world.

Withdrawing Troops from Iraq:

Partially fulfilling one of his major campaign promises that probably is one of the sharpest reversals from Bush's policy, Obama ordered the drawdown of troops in Iraq at a late February pit stop in Camp Lejune, N.C. "Let me say this as plainly as I can: by Aug. 31, 2010, our combat mission in Iraq will end," the president said on Feb. 27 in a gathering of troops.

Endangered Species Act:

The president authorized full scientific reviews of projects that might harm endangered wildlife and plants. Obama's memorandum overrides the Bush administration regulation that limits scientific reviews of projects that could harm endangered species.

While signing the act on March 3, Obama chided Bush's policies, saying that "For more than three decades, the Endangered Species Act has successfully protected our nation's most threatened wildlife. We should be looking for ways to improve it, not weaken it."

Oil & Gas Drilling Near National Parks:

Interior Secretary Ken Salazar announced in February that the government would withdraw oil and gas leases that were offered on 77 parcels of public land for drilling near national parks in Utah by the Bush administration and that are currently in court. "In its last weeks in office, the Bush administration rushed ahead to sell oil and gas leases at the doorstep of some of our nation's most treasured landscapes in Utah," Salazar said. "We need to responsibly develop our oil and gas supplies to help us reduce our dependence on foreign oil, but we must do so in a thoughtful and balanced way that allows us to protect our signature landscapes and cultural resources in places like Arches National Park, Canyonlands National Parks, Dinosaur National Monument, and Nine Mile Canyon, for future generations."

Labor Laws & Equal Pay:

Only ten days in office, Obama signed three executive orders that he said would "level the playing field" for labor unions and that would make unions easy to organize. Obama reversed a Bush order requiring federal contractors to post notice that workers can limit financial support of unions serving as their only bargaining representatives. Additionally, in undoing Bush's policies, Obama ordered that federal contractors offer jobs to current workers when contracts change and that federal contractors be prevented from being reimbursed for expenses meant to influence workers deciding whether to form a union and engage in collective bargaining. Obama's first law signed was also labor-related. The Equal Pay for Equal Work Bill was signed into law Jan. 29 and sought to end pay disparities between men and women.

Restrictions on Cuba:

The president relaxed travel, commerce and mail restrictions on Cuba, allowing American-Cuban families unlimited visits to the island and no restrictions on the amount of remittances they can send back. The White House also plans to expand telecommunications networks that link the United States and Cuba, as well as export of humanitarian items. President Bush tightened restrictions on Cuba in 2004, which been under U.S. embargo since 1962.
