If she runs, it will be because she wants to be president, just like everyone else.
desire is important, aptitude is as well.
====================================
The desire is what she supplies. The aptitude is what needs to be perceived by the voters. I think Hillary would make a good president, certainly better than anything that the Republicans are likely to conjure up. But I do not think she will run, unless, as I said, something really major happens to Obama. That is just not how US politics work. Hillary is vastly better qualified to be president than Palin. And we should not assume that Palin wants to run only because she wants to lead the country, either. She has perceived that she is being paid for her celebrity, and the more celebrity she has, the more she will be paid. Being a defeated presidential candidate would give her higher fees than she is getting now. There is also a biological clock a-ticking: men get craggy and end up looking like they had character, as Redford and John Wayne did. Women turn into dessicated old crones. Greta Garbo and Sofia Loren certainl know this well, and prefer to have the public remember them as they once were. Palin's struggle is to preserve her image while itcannot be belied by her actual appearance. The one certain thing is that Palin will get wrinkly and eventually will have all the sex appeal of Madeline Albright. By which I do not mean to demean the competence of Albright. I am referring to image, and image is what Palin is being paid to project. It's really all she has.

As for nuking Iran, it is really, really dumb to want to drop weapons of mass destruction on entire populations of other human beings. Iranians are people, just like CU4. Most of them do not hate the American people, though American policy towards Iran has as much to hate about it as Iranian policy towards the US govt. Iranians have not shot down airliners full of civilian passengers and called it a mistake. Iranians have never overthrown an elected US government and imposed a tinhorn puppet king on Americans for 25 years for the benefit of greedy Iranian oil companies. Iranians do not "hate our freedoms": they merely hate what we have done to their country.
