The two states had favoured Congress and UPA in 2009 general elections.
The CNN-IBN election tracker poll done by CSDS and Lokniti, says that the AIADMK-Left alliance is likely to win just over half the 39 seats in the state. The projected range for this alliance is 14-20, only a little more than the 10-14 seats projected for the DMK. The Congress is predicted to win 0-4 seats and "others" 5-9.
In Andhra Pradesh, the Congress had won 33 seats in 2009. But this time, its projected tally is 6-12, with the TRS being predicted to win seats in the same range.
However, the main battle will be between the Jagan Mohan Reddy-led YSR Congress (11-17) and the TDP (10-16) with "others" picking up 1-5 seats from the state's 42.
