Posted: 07/04/2008 - BUTTE, Montana (AP) -- Barack Obama is celebrating the 4th of July in Butte, Montana, attending a parade and picnic. It's a state that usually gives its three electoral votes to a Republican. Only two Democrats have carried Montana since 1948. Republicans typically take it for granted and Democrats usually write if off. But this year, Obama is spending a sizeable amount of time and money to try to win it.
