After watching Hillary Clinton, Barack Obama and John Edwards in Iowa, Mark Leibovich says the choice comes down to pronouns:

[Clinton] prefers the pronouns “I” and “me,” whereas Mr. Obama is more prone to use “we” or “us” and Mr. Edwards “them.” . . .

Mrs. Clinton’s “I” is a proxy for her message of experience. . . . Mr. Obama’s “us’” and “we” reflect his unity campaign. . . . “They have infiltrated everything,” Mr. Edwards shouts, right hand clenched in a fist around his microphone."

Stuart Rothenberg says Edwards just might win in Iowa but, regarding the fighting words, warns: "Given the North Carolina Democrat's rhetoric and agenda, an Edwards presidency would likely rip the nation apart - even further apart than Bush has torn it."

In Iowa, Mike Huckabee fights back against Mitt Romney -- er, decides not to -- er, sorta does -- okay, doesn't. Got that? His new (and positive) Iowa ads are here.

Back in New Hampshire, state GOP Chairman Fergus Cullen just called on Fox to include "all recognized major candidates" in its Jan. 6 debate. The release didn't say whether Cullen recognizes Ron Paul as major, but it says here (and in our in-box): He is.

UPDATE: The Conway Daily Sun endorsed Bill Richardson today:

In our opinion, this year's Democrats are stronger than we've ever seen, and out of three that we believe could be good presidents, we endorse N.M. Gov. Bill Richardson.

It boils down to this: Sen. Barack Obama and former Sen. John Edwards are clearly highly principled people of integrity, and in another race the Sun would have supported one of them.

While Obama and Edwards have the big media budgets, neither has the experience of Richardson. And as for Hillary Clinton, this is what fringe candidate and straight-talking former Sen. Mike Gravel says.

"The Clintons should read the Constitution, eight years is all they get."

A handful of years as senator for each of them simply does not stack up to Richardson's powerful resume as a former congressman, energy secretary, U.N. ambassador, and now, governor of New Mexico. . . .

The knock against Richardson is that he doesn't have the dynamic personality of Ronald Reagan or Bill Clinton, although in person he's funny and engaging. Asked about this rap and to compare himself to Bill Clinton, Richardson says, "Yes, Clinton can electrify a room, but I can get it done." We're convinced he can, and we ask you to join us in voting for him.

(The editorial, as transcribed by the Richardson website, says the Sun was the only New Hampshire paper to endorse John McCain in the 2000 Republican primary. That is incorrect. At a minimum, the Monitor and Telegraph both did.)
