While the Republican race is a lot more interesting in general, I have been paying less attention to their debates and strategies because apart from not-Giuliani, those candidates will be generally of the same strength and effectiveness as both a candidate and (potentially) a president. Too much is being made out of how weird it is that Romney is a Mormon and while Americans tend not to elect old people, McCain does not look or sound crazy-old.
On the Democrats' front, I am a big supporter of John Edwards because I like that he is staking out different framing/philosophical grounds for the political discussions. Not only is that good because he is approaching it correctly but it is a generally good thing for candidates to disagree on these fundamental issues of how to approach subjects, not just the end policies. This is a good idea because in real life, those are what the disputes amount to. No one wants children to go without health care or for poor people to starve or to waste money on ineffective military ventures, the actual disagreement is about how to decide what is effective and how best to improve people's lives. That is why the whole phenomenon of "scoring political points" strikes most people as stupid.
However, from a purely political stand point, I think that Edwards is dead in the water. He is consistently polling third and with a growing spread between him and Obama/Clinton. The only way to make up that ground effectively is to attack the front runner. With Obama positioned second but close, he stands to gain from staying on a positive message, allowing Edwards to draw blood on Clinton and staying above the "common politics" both of them will engage in. Given the incentives and their likely results, I think that Obama, in spite of his milquetoast rhetoric at present is in a very strong position as the primaries play out. While Hillary Clinton has the advantage right now, she will have to defend against attacks from both her right and her left and there is not a lot of room for her support to grow as there are more people absolutely unwilling to vote for her than there are for any other candidate.
