Actually, the choices aren't so much ours as they are the choices of editors and popular bloggers. See Making news or reporting news? They are the ones who choose the so-called front-runners and give more coverage to them.
So, being a not-so-popular blogger, I'll give my own list of front-runners. However, later I will give you an alternative for choosing a presidential candidate, by-passing all of us media know-it-alls.
My order does not reflect my current preferences. It's just as they pop into my mind.
Hillary Clinton has some good ideas and some bad ideas. From what I've read, she is the one coming up with concrete proposals for many domestic issues, like health care. On the other hand, she has cast votes in the Senate that have led us into the current mess in Iraq. I have not seen any concrete proposals for a smooth extrication from Iraq.
Bill Richardson, Governor of New Mexico, has experience in governance. That is, making government work to the benefit of most of the people. I favor this qualification for President over any other, including "foreign policy experience". The Current Occupant certainly didn't have any of that and still doesn't after seven years on the job. I would have to examine Richardson's record more to see how well he governed. It would be nice if the major newspapers gave him as much coverage as Clinton and Obama.
All the Republicans are more of the same Goofy Old Party that has gotten us into many of our current problems. The only Republican I might consider voting for is Ron Paul, but I have only two reasons. As a libertarian, he has an independent streak that is refreshing in the current "The President's way or the highway" mindset. He did vote against the Iraq War, my second reason for favoring him. However, libertarians minimize common good, something in short supply among Republicans.
What alternatives to we have, outside of getting involved in a party or an individual campaign? There is a group called Unity08 that will hold an online nominating convention in June 2008. Once the convention selects a candidate pair, Unity08 will endeavor to put them on the ballot in every state. Visit Unity08 for more details on participating in the convention.
My own quirky choices: Kathleen Sebelius, David Brooks, Thomas Friedman, or Olympia Snowe. The thinking of any of these is better than many who are currently more prominent in presidential politics. Any pairing from this selection of politician-politician or politician-journalist would give us a more serious discussion of the issues than is currently available.
