I point you to Campaign Spot’s Romney Guy who says:

The McCain, Thompson, and Guiliani camps vehemently deny any responsibility for these recent push polls, and for now, they are probably telling the truth.

I’ll fearlessly predict we’ll see a lot more arrows pointing in one or another camp’s direction. As Mark points out in his piece, the polling world is “incestuous” with overlaps. We ought to all — reporters, campaigns, men on the street in primary states — be careful about jumping to conclusions.

This is Jim’s guess:

If and when the New Hampshire Attorney General names someone, I suspect we’ll find somebody with deep pockets, a relatively new desire to play in the political game, and little concern about long-term relationships in the GOP.
