Stage 20 - Grenoble - Grenoble 42.5 km

Can Andy Schleck hang on to his 57" lead over Australian Cadel Evans in today's time trial in Grenoble? On the  Tour de France official website 53.43% of voters think that Evans will take the Yellow Jersey after the short stage. Evans is definitely a superior time trailer but 42 km isn't much to work with. Or will Frank Schleck steal the jersey from his brother? If I believed in miracles I'd have Thomas Voeckler take back the yellow after his scrappy fight to keep it on his back throughout much of this year's Tour (he wore the Yellow 10 days in a row).
