found these two points interesting:

CBS News;

Few of the self-described Republicans who turned out to vote in the Democratic primaries in North Carolina and Indiana seem to actually support the candidate for whom they voted. Perhaps most intriguingly, however, is an apparent effort by Republicans to promote Clinton's candidacy when they feel Obama is the better nominee.

In each state Clinton carried the vote of Republican voters - 52 to 44 percent for Obama in Indiana, and 61 to 32 percent in North Carolina. Republicans made up only 5 percent in North Carolina's Democratic primary electorate, but made up 11 percent of the vote in the Indiana Democratic primary, enough to provide Clinton's expected margin of victory. 

Obama email before finals in last night;

Indiana remains too close to call.  But what is clear is that we did much better than all the punditry predicted, despite Republicans changing parties to support Senator Clinton, believing she would be easier for Senator McCain to defeat.
