Rajasthan is set to witness a three-cornered fight in the assembly polls likely to be held later this year with the Aam Aadmi Party (AAP) on Thursday setting in motion preparations for the launch of its foray in the state, currently ruled by the Congress. AAP's poll strategist Sandeep Pathak held a crucial meeting with the party's Rajasthan unit leaders and volunteers here, and asked them to pull up their socks to make the party's foray in the Congress-ruled state a success.
