Damn it. I had a big timeline typed up, but the Atlas ate it. Anyway, red is Feingold, blue is Warner, green is Lynch and yellow is Harkin. Warner drops out after losing Pennsylvania, so all remaining states go to Feingold. (Bayh and Strickland drop out after failing to win Michigan, Harkin after Florida, although why he stayed in so long is a mystery since he was irrelevant everywhere except Iowa, which only he and Feingold seriously contested. Lynch drops out after winning Maine, going out on a winning note.)
