The Hill is almost reporting that Barack Obama will appoint Representative Ray LaHood of Illinois as Transportation Secretary.
In principle, I think this is a great slot for a bipartisan pick. In practice, Democrats tend to be better on transportation issues than Republicans, but there isn’t actually a ton of ideological linkage between these issues and the broad disagreements between the parties. You could think abortion is murder, and also that investment in high-speed rail would be a good idea. Or you could favor tax cuts and congestion pricing on roads. And of course lots of Democrats have terrible views on transportation issues.
As for LaHood, he’s no Paul Weyrich, but he did break with the GOP to support the Passenger Rail Investment Act and the Saving Energy Through Public Transportation Act so that seems promising.
