"I am not against anybody", he stressed.
While three TV channels predicted 80 to 114 seats for Modi's BJP, short of the half-way mark in the 224-member house, polls also forecast 22-43 seats for a regional group, Janata Dal (S), which could emerge as a kingmaker.
JD-S chief and former Prime Minister H D Deve Gowda, his wife Chennamma and second son H D Revanna cast their votes in their hometown Holenarsipura in Hassan district. Eight major polls Saturday predicted a median 26 seats for the party - with the higher end of the predicted range in some polls reaching 35-40 - a critical mass in a situation in which almost every poll sees both the Congress and the BJP falling short of the halfway mark of 112.
The Congress Legislature Party (CLP) would meet on May 16 or 17 and the party will take a decision after reviewing the results, he said.
He claimed that there is a strong wave in BJP's favour.
The turnout was the highest-ever in Karnataka since the 1952 Assembly elections, he said.
But all eyes are on the JD (Secular) of former prime minister HD Deve Gowda, give the predictions of a hung assembly in the state.
"From very beginning for last six months I have been telling that Congress party will get majority".
Speaking to reporters in Chamundeshwari constituency, one of the two seats from where he contested, Mr Siddaramaiah said, "This will be my last election". Relying on poll of polls is like a person who can't swim crossing a river on foot relying on a statistician who told him the average depth of the river is 4 feet. However, before the formal announcement of the results, several agencies conducted exit polls, predicting the outcome. Please note an average of 6+4+2 is 4.
Karnataka polling is seen as a crucial test ahead of the Lok Sabha elections next year. "At 6 feet you drown". Even, BJP's close chief ministerial runner Yeddyurappa confirmed that is a party is winning by a big margin of 150 or 130 in this Karnataka Election.
While pollsters have predicted a hung Assembly in Karnataka, that party that wins the most number of seats in Old Mysore, Bombay-Karnataka and Coastal Karnataka regions, is likely to form the next government.
Siddaramaiah's statement triggered speculation that Congress is anticipating a fractured verdict and is playing the Dalit card to negotiate a post-poll tie up with the JD (S).
