Beating a dead horse, but I suppose if there was one issue on which I felt strongly, it would be the fiscal situation. This 1 hour lecture puts it in the proper perspective and why it matters.
Irrespective of the demerits of various Presidents, least of all Bush, but now also our current Prez, for me it's the overriding issue, and I believe proper stewardship of the economy and the fiscal situation is what matters most.
