Happy news for the Clinton family as they prepare to sit down for a nice private Thanksgiving dinner on Thursday, just Hillary and Bill and Chelsea and her husband and their daughter and each family member's communications lead and assistants tasked with tracking each of the main dishes and sides and pollsters who can kibosh things that don't test well in New Hampshire and the film crews looking to capture normal, everyday Hillary Clinton. Oh, and the Secret Service agents. Cozy family meal.

That good news? Clinton's lead in Iowa has held steady in Quinnipiac University polling over the last month. The school's new survey of the Democratic race shows that Clinton's lead over Bernie Sanders is about what it was when they polled in October -- a marked improvement over the month before that.

That's one pollster, mind you. The Real Clear Politics polling average shows the sort of positive trend that Clinton doesn't want to see.

That said, though, it's still very different than what it was in 2007. That year, there was a tight three-way race for the state. Clinton's current lead is much more substantial.

What's interesting, though, are the fractures within the Iowa Democratic party. Men like Bernie, women like Hillary. Moderates like Hillary, liberals like Bernie. It's pretty consistent.

Those splits are pretty consistent, too, since Sanders emerged as a viable contender.

Even more remarkable is the split between left and right in the state. Quinnipiac's survey of Republicans asked about the same top issues as this poll of Democrats. And the things that are important to each differ wildly.

Both groups are worried most about the economy. But Republicans are far more worried about terrorism than Democrats; only 5 percent of Democrats -- and 3 percent of liberals -- listed that as their top concern. Three times as many Democrats said climate change was their top concern in the upcoming election -- the top concern of no one on the right.

If that split holds, it will be fascinating to see how the general election candidates navigate that gulf. Sure, most partisans will simply vote for their party. But if either side needs to energize the base, how do they end up talking about something that doesn't turn off the other half of the country?

Those are worries for another time. For now, Clinton and her coterie can simply tuck into some turkey, content with the state of Iowa.
