Presidential Primaries Make Way for Fall Campaign

In Kentucky and Oregon yesterday, white voters dominated, but with very different results. Hillary Clinton's Kentucky victory was overwhelming, and nearly half the state's Democrats said they would not support Barack Obama against John McCain. Obama now claims a majority of elected convention delegates. Today, they're both in Florida, as McCain was yesterday. It's one of the crucial "swing states" that could be decisive in November, just as it's been in the past. It will take 270 electoral votes to get to the White House, but each candidate is looking at separate contests in 50 different states. Has the calculus changed since 2000 and 2004, two of the closest elections in history? We look at red states, blue states and swing states around the country.
