The whole issue of why a 'vote of comfidence' is the only way out is bacause the BJP and the Left cannot be seen as supporting a non confidence motion against the UPA . For Karat and Co nothing is more important than to teach a lesson to MMS for ditching them. Since the Left is greatest evil in this country that must be banished ... the BJP/NDA should walk out/ abstain during the 'confidence motion' and get let 59 Left MPS try to look foolish against the numbers the the UPA puts up . For the BJP a UPA Government or a UPA caretaker government will not make any difference.
