Obama: Running to help other Dems win

Obama doesn't want to just challenge McCain in states that voted for Bush (link). He wants to support down slate Democrats who he will need to advance Democratic policies. So he will be campaigning even in some states where he doesn't have much of a realistic chance of winning but where other Dems could benefit from his help.

That's the kind of long-term, strategic thinking that has been absent in national level Democratic politics and its one of the reasons I feel optimistic about an Obama presidency. He understands that a general is only as strong as his troops.
