Addressing a BJP legislative party meeting, Raje said there was no need to lose hope over the bypolls, in which the BJP lost two Lok Sabha seats and one Assembly constituency to the Congress, party sources said.
BJP state president and MLA Ashok Parnami said the party was analysing the results.
The government left no stone unturned in carrying out development in the state and hoped that the party would retain power in the next Assembly elections due later this year, he added.
The Congress won the Ajmer and the Alwar Lok Sabha seats and the Mandalgarh Assembly constituency in recently held bypolls.
The seats were with the BJP earlier.
