KANSAS CITY, Mo. -- After Sen. John Kerry's win in New Hampshire, the presidential primary heads to Missouri and six other states, which will all vote Feb. 3.

A just-released survey of likely Missouri primary voters shows the state remains up for grabs, KMBC's Micheal Mahoney reported.

More than one-third of those surveyed said they were undecided about who they will support. The only candidate who had double-digit numbers was Sen. John Kerry, who pulled a quarter of the survey support. The rest of the field, including Edwards, Dean, Clark and Lieberman, were all in single digits.

Scott Burnett, a Democratic activist who has worked in many campaigns, said no one expected Missouri to be this competitive.

"We're a surprise here in Missouri, now that Gephardt dropped out. Everybody here is scrambling," he said.

The top issues in the minds of the polled voters were the economy, with 21 percent saying it was the top issue; health care, which was the most important idea for 10 percent; the war in Iraq was tops for 8 percent; and terrorism was the highest concern for 6 percent of those polled.

Just over half of those polled -- 51 percent -- said they did not believe the war in Iraq was justified.

Kerry will be in Missouri on Wednesday to campaign. He is expected to stop in Kansas City on Saturday.
