I'm leery about running Condi Rice for president. I don't think it's been proven that she is presidential material. There's more to the presidency than sitting in the Oval Office making decisions. A president needs to lead - communicate with Americans, even inspire or steady them, as President Bush did after 9/11. A president needs to tell Americans where he wants to lead them and how he means to get there. I don't know that Condi Rice can do it.
There are a few problems to electing Condoleezza Rice:
She's a woman. Yes, even in our politically correct age that's something to be overcome.
No one has voted for her in all her life. She has no electoral experience, no one knows if she is a good campaigner. The first office you run for should never be the presidency, except in extreme circumstances - like being a general-hero of World War II. Condi Rice is good, but she's no Dwight D. Eisenhower.
She's unmarried. Okay, presidents should be married, but is that any reason not to vote for her? It does, however, bring up a different point, which is that Condi has never married, never had children, and spent her entire adult life in academia and government. Her ability to relate to the lives of the vast majority of Americans, and their ability to relate to hers, is seriously in question.
She believes the government should not ban abortion. BIG red flag. President Bush thinks abortion should be banned completely, with a few rare exceptions. A lot of pro-lifers may disagree with him, but most will vote for him anyway. Condi Rice's position is farther than many pro-lifers are willing to bend.
Unfortunately in this day and age, an untelegenic cannot make it to the White House easily.
