I didn't but I discovered that in this interview with former Bush adviser Karl Rove.
Mr Rove's interview with Fox's Bill O'Reilly is a great guide to the current state of the election. Noting that Clinton needs to win 58% of the delegates left on the table, Rove believes that Obama is still likely to get the Democrat nomination. Although the former First Lady will probably win big in the delegate-rich swing state of Pennsylvania - because it is whiter, more blue collar, less affluent - that contest is seven weeks away and intervening primaries will return some momentum to the frontrunner. The next contests of Wyoming and Mississippi are likely to strongly favour Obama, for example.
Rove worries that McCain will soon find himself relegated to page fourteen status while the Democrat contest will still be headlining. Unless the Democrat contest leaves scars on the eventual nominee this period may harm the GOP's hopes of keeping the White House.
The two note a hard-hitting (but effective) anti-Clinton ad that is playing in Mississippi from the Obama campaign. What happened to the hopefulness of Obama, they laugh?
