Top Obama Flip-Flops

2. No Child Left Behind Clinton voted in favor of the 2002 education bill that focused on raising student achievement levels, hailing the measure as "a major step forward." She now attacks the law at campaign rallies and meetings with teachers, describing it as a "test, test, test" approach.

3. Ending the war in Iraq In June 2006, Clinton restated her long-standing opposition to establishing timetables for withdrawing U.S. forces in Iraq. In a Jan. 15, 2008, Democratic debate in Las Vegas, she proposed to "start withdrawing" troops within 60 days of her inauguration, to bring out "one or two brigades a month" and to have "nearly all of the troops out" by the end of 2009.

4 . Driver's licenses for illegal immigrants In a campaign statement on Oct. 31, 2007, Clinton expressed support for a plan by New York Gov. Eliot L. Spitzer (D) to offer limited driver's licenses to illegal immigrants, after going back and forth on the matter in a televised debate. In a Nov. 15, 2007, televised debate from Nevada, she replied with a simple "no" when asked if she approved the driver's license idea in the absence of comprehensive immigration changes.

5. Florida and Michigan delegates In September 2007, the Clinton campaign formally pledged not to participate in primary or caucus elections staged before Feb. 5, 2008, in defiance of Democratic National Committee rules. She now says delegates from Florida and Michigan should be seated at the Democratic National Convention, despite their flouting of rules that all the major Democratic candidates endorsed.
