My gut feel says yes.
UPA or for that matter Congress not getting a clear lead is an indication that all the talk about all the things they have done in last 5 years is utter rubbish! A seriously hung parliament is an indication of this.
If nothing else, the President should invite BJP to form the government. But President obviously wont.. given the strong Congress ties.
But I have a strong feeling (and I really hope I am proved right for once!) that BJP just might surprise all the exit polls in a positive way.
The economy needs a big time boost and if the stock market behaviour yesterday is any indication, even the corporate India wants NDA in power. And Manmohan Singh right now.. the only boost he can offer is to himself (of the kind which is the secret of their energy for the some cricketers!)
