Soon after I wrote yesterday's posting--in which I questioned whether the Democratic convention was producing enough red-meat attacks against John McCain--I ran into Senator Dick Durbin, the Illinois Democrat and No. 2 in the Senate. I asked whether the Obama people planning the convention had made the slightest of strategic errors by not striking at McCain in a harsher manner. No, no, no, said Durbin, who has been one of Barack Obama's most enthusiastic supporters in Democratic officialdom. "They're cutting ads right now that will be a lot sharper," he noted, referring to spots that would come out after the convention. "We need to come out of here with a positive message."

Well, we'll have to see how strong those ads are. But on Thursday night, the main speakers at the convention generally stuck to the usual practice: praise McCain's heroism, courage and service to the country and then say the problem with him is that he has a few bad ideas. Joe Biden, who as veep-mate is supposed to be the lead attack dog, went on about how McCain's courage "amazes" him and noted that his friendship with McCain transcends politics. As I've written before, this strategy of heaping praise on McCain the man and then questioning McCain's ideas may place the Dems in a corner. McCain attacks Obama for being a traitor. He says Obama is so ambitious he is willing to lose a war to win an election. That's a damn ugly charge. It's a vicious indictment of Obama's character. What do the Obama-ites do? They say McCain is a man of solidity but they disagree with his policy notions. Not very even, right?

So don't the Dems then have to ratchet up? Show voters he's a phony maverick or a warmonger or completely out of touch (with the Internet, the economy, take your choice)? After all, if the choice for the voters is a good man with some bad ideas or a bad man with some good ideas, wouldn't many choose the former?

Hours after Biden's speech, I found myself in a hotel restaurant at closing time with an assortment of reporters and political ops. I raised this point, and a Democratic political consultant (not the one I mentioned yesterday) disagreed. This person said that there had been a loot of private polling done on the Democratic side that indicates that on-the-fence voters would not buy a direct slam on McCain and that they would not absorb any negative information about him unless the attacker paid tribute to McCain's military service. The consultant was adamant on this point. S/he maintained that the polling did show that voter perceptions of McCain could be changed to benefit Obama, if the attack was crafted the right way and McCain was not merely blasted.

I don't have access to this empirical data. It could be overwhelmingly convincing. (My table-mate did not reveal who had done this polling.) But if the Democratic assault on McCain has to be nuanced and tempered with praise, that could be quite tricky for the Obama campaign to pull off. It's clear that the McCain attack on Obama ain't gonna be subtle. Not next week in St. Paul. And certainly not in the weeks after that.
