Yeddyurappa's arrest: Advani rath yatra spoiler?

For days, BJP leader LK Advani has been travelling around the country on his whirlwind yatra against corruption. In every rally, he is repeatedly targetting the UPA government on various scams. But what seems to be taking the steam out of his rath yatra, is the arrest of former Karnataka chief minister BS Yeddyurappa on corruption charges. Mr Advani has not made a single reference to Yeddyurappa's arrest, choosing to maintain a rather obvious silence.
