Good morning, New Orleans, how are ya?

New Orleans, by The Highwaymen. That's Willie Nelson, Johnny Cash, Waylon Jennings, and Kris Kristofferson.

Labor Day was beautiful here in D.C. It looks like Gustav will not bring disaster on the scale of Katrina, though I'm sure many people lost much and there are days of rain and flooding and more hurricanes ahead.

Our two possible next presidents responded differently. Both posted ways to volunteer on their campaign websites. McCain headed to Mississippi, apparently to make sure there will be photos of himself helping someone. Obama visited Iowa after the flooding emergency there settled. He says "the important thing to do now is to stay clear of the area until things have settled down... The thing that I always am concerned about in the middle of a storm is whether we're drawing resources away from folks on the ground because the Secret Service and various security requirements sometimes it pulls police, fire and other departments away from concentrating on the job."

In Katrina, many of the people who didn't get out in time either didn't have transportation or delayed because they were trying to find a way to save their pets. This time New Orleans and Louisiana mobilized. A fleet of buses and Amtrak trains evacuated people who don't have cars. Volunteers helped evacuate animals. A few more weekend thoughts about our possible future presidents. They have very different approaches to building our national infrastructure, all summarized right here.

In 2007, McCain and Bush opposed the $23 billion Water Resources Development Act, which funded improvements to rivers, harbors, levees and flood control projects. Congress overrode Bush's veto and the bill passed. In 2002, McCain proposed abolishing Amtrak and privatizing our rail system.

Obama supported the 2007 Water Resources Development Act. He also proposes to strengthen urban infrastructure, highways, public transportation, bike paths, pedestrian friendly streets, and increase funding to Amtrak.
