I have a story up this morning about how — for now — Barack Obama and John Edwards are helping each other out by targeting Hillary Clinton. The three Democrats are locked in a tight battle to win the Iowa caucus, now less than two months away.

Since Edwards and Obama, using very different styles, went after Clinton at last week's debate, her lead in several polls has shrunk, though she is still by all accounts the frontrunner. Her campaign points this out this morning with a "lead unchanged" headline over at HillaryHub.

This weekend all of the major Democratic candidates will speak to Iowa Democrats at the party's Jefferson-Jackson dinner, one of their last opportunities to make a broad appeal to party faithful before the Jan. 3 caucus.

Some Iowa Democrats today will get a chance to hear from Clinton's biggest advocate — the former president.
