No one should be even mildly surprised that Cong opted for Prez Rule, rather than first seeing whether BJP, which has the most seats, can cobble together a govt. Cong, as always, never missses a chance to show thier treacherous side, especially when it comes to "Power". With their own Guv and their own Prez, Cong can do any darned thing they want and no one can do diddly.
This all is just the dirty politics which congress has been practising since long, what thet did in GOA, what they did in Jharkhand is enough to state why not the same treatment in Karnataka.... because you know.... the benificiary would be BJP.... Just the Dirty Political example of Congress and SONIA at least Rahul should have objected it..... HUH
