Addressing a press conference here on the last day of campaigning, Shah said that question of an alliance with any party doesn't arise because the BJP on its own will win over 130 seats.
Shah's statement hold significance as almost all opinion polls have predicted a fractured verdict with a hung assembly in Karnataka. Former prime minister Deve Gowda's JD(S) may emerge as the kingmaker, pre-poll surveys have projected.
Attacking the incumbent Siddaramaiah government, Shah said: "The Karnataka government has done nothing for the farmers and they are not even ready to give answers for their failure. We have experienced the anger of the people of Karnataka for Siddaramaiah government, as it has not done anything for the state."
"In the last 5 years, the ruling Congress has proved to be the most unsuccessful government after the independence."
Shah also hit out at the Congress over the fake voter ID card row and alleged it wants to win Karnataka elections in an undemocratic manner.
"Congress is trying to win elections with the undemocratic ways. Recovery of Voter ID cards in Rajarajeshwari Nagar shows how desperately it wants to win the polls. I want to alert those whose fake IDs have been made that they should not fall in the Congress' trap and disturb polls," he said.
In his presser, Shah also referred to his road show in Badami from where Chief Minister Siddaramaiah is in the fray in the Karnataka assembly polls.
"We have ended our campaign with a historic roadshow in Badami. Siddaramaiah has changed his constituency and he is contesting in Badami. He will lose there too. His government is a complete failure," he said.
