Jonathan Martin writes in Politico this afternoon that Obama will find more sympathetic voter terrain in Indiana, which has a surprisingly high urban makeup among other traits.  And - just as important if not more so - he's on equal footing with Clinton from the start.  No 20 point come-from-behind gap to contend with, no Clinton home-state advantages to overcome.

Anyway, it's an interesting read...I'll share a few quotes below, but here's the link:

For Obama, the raw math suggests a slight advantage. Upwards of 25 percent of the primary vote will come out of just two counties: Marion and Lake. The first is home to Indianapolis, the capital and state’s largest city, and the second is home to industrial Gary, located in the northwest corner of the state and part of the Chicago media market.

Both will strongly favor the Illinois senator, predict Indiana political observers, thanks in part to large African-American populations.

...contrary to some stereotypes of the state, Indiana’s population is largely packed into small and medium cities — not spread out in rural areas. It’s more than 70 percent urban, and 30 of the state’s counties produce 81 percent of the vote.
