Indiana still too close to call
Nearly all of the remaining votes are in Lake County—the area including and surrounding Gary. Some 220,000 votes are yet to be counted, with Clinton leading currently by about 40,000. Since Gary is the Chicago area, Obama is expected to have an advantage there. If Clinton wins, it'll likely be by less than the 4% lead she currently has.
This is the beginning of the end, hopefully. Clinton, I suspect, might just want to go out on a high note. She's expected to win West Virginia big next Tuesday, and then win Kentucky big on May 20. Obama is expected to win Oregon big on May 20, so that might be the best time for Clinton to announce her concession. Of course, she also might continue to rend the party in two by prolonging the primaries unnecessarily, flogging Jeremiah Wright against Barack Obama the way Al Gore flogged Willie Horton against Michael Dukakis in 1988. (Remember that? Maybe you thought it was the George H.W. Bush campaign that dug up the Willie Horton garbage, but it was actually the Democratic presidential contender, Senator Al Gore Jr. of Tennessee. But we'll never learn, will we?)
Indiana could go either way, but effectively it's a flop for Hillary Clinton.
