You may be right. Communists withdrew support to the UPA after re-confirming that SP will support UPA immediately. After UPA getting support from SP, Communists went to Mayawati and the rest is history !!!
The games Communist play in this country is very amusing. Due to this drama written during Cong-I and Communists "earlier meetings" before parting ways was just to stop the BJP to align with Mayawati after elections in future.In otherwords communists have permanenetly blocked the BJPs chances to cosyup with NDA allies as well as BSP, thus clearing the road blocks for the Cong-I to form the government once again in the name of saving secularism!!! If BJP wants to rule india BJP ruled states must send maximum MPs otherwise BJP will be left with palying second fiddle or sit in the opposition.
