NEW YORK (CNN) –- As Super Tuesday approached, many political observers suggested Barack Obama would run strong in states that hold caucuses rather than primaries -– the kind of contests that tend to attract only the most committed liberal party activists.
So far, that prediction seems right on target.
Obama has earned victories in all of the caucus states that have so far been called: Colorado, Kansas, North Dakota and Idaho.
CNN has not called a winner in the remaining caucus states, Minnesota and Alaska.
