Obama ramping up campaign in Missouri

WASHINGTON (AP) -- Democratic presidential hopeful Barack Obama is ramping up his campaign organization in Missouri.

The Illinois senator's campaign is placing a full-time director in Missouri and plans to open offices in St. Louis and Kansas City in the next few weeks.

Obama has raised nearly $2.5 million from Missouri donors, more than any other Democratic presidential candidate.

At least 20 states -- including Missouri -- plan to hold presidential primaries or caucuses on February 5th.
