Republican presidential candidates showed strong support for the military mission in Iraq but expressed concerns about the Bush administration's handling of the war during a calm first debate. The debate, held at the Ronald Reagan presidential library in California, revealed some differences among the 10 candidates on social issues such as abortion. Most of the candidates emphasized the importance of achieving victory in Iraq, contrasting with Democratic candidates who called for a swift end to the war in their own debate. Senator John McCain, a strong advocate for the war, emphasized the need to win in Iraq to prevent chaos and genocide. Rudolph Giuliani, the ex-mayor of New York and the top Republican candidate in national polls, stated that it is a mistake to back down in the fight against terrorism. However, other candidates have questioned the handling of the war by Bush and his administration. McCain criticized the management of the war for four years, attributing errors in judgment to prioritizing advice from civilians over generals. Former Arkansas Governor also expressed similar concerns about the decision-making process. The debate in California took place in a grim political atmosphere for Republicans, following their loss of power in Congress in November's elections. Polls indicate widespread public dissatisfaction with President Bush, the Iraq war, and Republicans in general, 18 months before the 2008 presidential election. This has forced candidates to carefully consider whether to align themselves with Bush or his policies. Former Massachusetts Gov Mitt Romney, despite polling in single digits nationally, has gained prominence in the race due to strong fundraising and support from the establishment. He emphasized the importance of prioritizing bringing troops home from Iraq, regardless of public opinion on the war. However, I also understand that we must be cautious in how we bring these issues to light so as not to create a situation that would necessitate revisiting them," Romney stated. Many conservatives have expressed dissatisfaction with the Republican presidential candidates, particularly Giuliani for his support of gay rights and abortion rights, and Romney for his shifting stance on these issues. Romney justified his change in position on abortion rights as a genuine shift in opinion, stating, "I changed my mind." The majority of candidates indicated their support for overturning the Supreme Court ruling that legalized abortion. Giuliani expressed his acceptance of abortion but believed it should be decided by individual states. Virginia Gov James Gilmore supported abortion rights in the early stages of pregnancy but had imposed restrictions on abortion while in office. The debate held at the Reagan library prompted candidates to honor Reagan's legacy and conservative values. Nancy Reagan and California Gov Arnold Schwarzenegger were in attendance, but their support for federal funding for stem cell research did not sway many candidates. Additional individuals who took part in the event included Kansas Senator Sam Brownback, Representatives Tom Tancredo of Colorado, Ron Paul of Texas, and Duncan Hunter of California, as well as former Governor Tommy Thompson of Wisconsin.
