There was a brawl today inside Bethlehem's Church of the Nativity.

If you're in Iowa this week, you'll need to watch out for campaign buses. Several Republican candidates are on bus tours of the state — including former Massachusetts Gov. Mitt Romney and former House Speaker Newt Gingrich.

For Gingrich, it's something of a comeback tour. After leading in the polls, he's had setbacks in recent days. Negative campaign ads by his opponents have hurt him with some voters. And news stories have raised questions on everything from his health-care stance to his first divorce, more than 30 years ago.

On Wednesday morning, Mitt Romney was getting an early start to campaigning in eastern Iowa, meeting and greeting voters having breakfast or just getting a caffeine boost at Elly's Tea and Coffee in Muscatine.

Good morning.

Our early headlines have ranged widely, subject-wise:

-- Weeping, Wailing And Imagery In Pyongyang For Kim Jong Il's Funeral.

-- Rev. Billy Graham Makes Top 10 'Most Admired' List For 55th Time.

Campaign buses loaded with Republican presidential hopefuls and their entourages are rolling across Iowa as the candidates hope some face time with GOP voters will help boost their chances in the Jan. 3 caucuses.

The main issue for many Iowa voters is the economy. But there's a sleeper issue emerging: immigration reform.

Iowa's Hispanic population is surging and Republican candidates are struggling with how best to deal with voter concerns.

The chief of Iran's navy warned Wednesday that his country can easily close the strategic Strait of Hormuz, the Persian Gulf channel where a sixth of the world's oil flows.

It was the second such warning in two days — and a Saudi official said Gulf Arab nations are ready to step in and offset any potential loss of Iranian crude in the world markets.

On Tuesday, Iran's vice president, Mohamed Reza Rahimi, threatened to close the strait, cutting off oil exports, if the West imposes sanctions on Iran's oil shipments.

"The Rev. Billy Graham has never finished first, but has been in the top 10 more than any other man — 55 times since 1955." This year, Gallup puts Graham at No. 4. He was mentioned by 2 percent of those surveyed.
