If I’m John Kerry, I want Howard Dean to remain in the presidential race as long as John Edwards keeps going. It’s not unreasonable to believe Edwards would have taken Wisconsin in the absence of Dean. (Then again, maybe not: Dean voters are very possibly motivated by loyalty to Dean’s antiwar position and wouldn’t transfer their allegiance to either Kerry or Edwards.) At any rate, Dean’s presence helps split whatever anti-Kerry sentiment is out there and makes Kerry’s nomination all the more likely.
