JDS and BJP are scared of mid term elections. JDS may have fared well in the recent Urban Local Bodies elections, but they had not done well in the ZP elections. BJP also didn't do well in either of these elections. Though Congress didn't do well in the recent Urban bodies elections when compared to 2001, they improved their votes when compared to the 2004 elections. Congress won 1,600 seats and JDS won 1,400 seats, making BJP a distant third.
JDS and BJP wouldn't want mid term polls and will find a way out to continue in power. Karnataka be damned.
