My apologies in advance to all remaining Nader supporters
I know I'm one of those guys who just never wanted to see Nader run, one of those guys whose reasons were strategic and visceral. I'm not going to lie like I did this analysis up front, but I would like you to consider for a moment how effective a President Nader would be. Not just what principles he espouses; if you're going to judge him strictly on what he says, you might as well judge Bush the same way (and I might as well start saving for that one-way ticket).
Does he really have the judgment you need to run something like the United States of America? Seriously consider the evidence of his current behavior (this is the same standard you should judge all the candidates by, in my opinion). That he needs support from the most regressive elements in politics may be worse than the fact that he accepts it. It shows he doesn't have the support his agenda does. He attacks and disrupts those who are most likely to consider his views, the moderate and progressives that have shown him such appreciation before now…and does so by saying they're the same as those who are funding him! He makes himself indebted to the most aggressively conservative among us, those least likely to help him, those most likely to demand outside that agenda of him.
How far forward do you he will be able to take your agenda with no real allies?
A man as intelligent as Nader knows the answer to this as well as you and I. I do not believe he is planning to fail. Therefore success must mean something other than winning the elections…I'm just describing behavior and inevitable consequences. Based on what I see, I can't force myself to believe he is actually running for President. But if he won, seriously, could he run the country? You shouldn't vote for Nader unless you can honestly say "yes."
