I’ve also seen exit polls in Indiana and North Carolina and other polls that supposedly measure the Wright Effect on Obama. These polls and others provide us with information about what voters are telling pollsters. They cannot prove the existence of a causality, in a sense that Wright as an issue made this or that individual vote for Clinton.

Here is my take: Many of these voters were predispossed to voting against Obama and were searching for an excuse to do that. And along came Wright. Obama clearly has a problem with these voters. But my guess is that in a race between Clinton and McCain, many of these voters would have searched for excuses not to vote for Clinton. And I also think that these are mostly older voters whose impact on the outcome of the presidential race will be marginal.

Bottom Line is that based on the outcome today, Obama is on his way to getting the Democratic nomination. And the presidential race will be his to lose.
