Do I think that McCain or most in Washington truly "fear" Obama at the level that many of us do? Likely not, but you really do have to be careful how you play certain things regarding being "scared" of him in terms of words straight from McCain.
This is probably overblown by ticked off Freepers, but if it proves to be troublesome then you can always use this to make the questions of truthfulness and judgment even stronger, i.e. I believe him to be a "decent" person, so the American people deserve coming clean on these associations, plans for the future etc.
And as for the truly ticked off Freepers that claim they will not vote for McCain now, do you realize that you are mad because he didn't jump on a comment about "fearing" an Obama presidency, yet you are willing to be complicit in electing this dangerous Marxist because of a comment at a town hall rally?
