Barack Obama is beginning a two-week bus tour that will take him to states that have either leaned Republican or have been out of reach for Democrats in recent years--North Carolina and Missouri, to name two. Often candidates talk of expanding the map (see Kerry, 2004 and Virginia) but Obama has the resources, volunteer network and the potential appeal to not just talk about it, but perhaps do it.

A Republican strategist said that, according to party monitoring services, Mr. Obama’s campaign had inquired about advertising rates in 25 states, including traditionally Republican states like Georgia, Mississippi and North Carolina. That would constitute a very large purchase. President Bush, whose 2004 campaign had the most expensive advertising drive in presidential history, usually ran commercials in a maximum of 17 states.

 It is too early to tell yet, but a good sign for Democrats that Obama is not just talking about these states, but taking his campaign there.
