The mathematics for the Presidential election

New Delhi: The Presidential election will be held on July 19, the Election Commission announced on Tuesday, setting the ball rolling for the process to decide on who would be the next occupant of the Rashtrapati Bhavan. All eyes are now on Congress chief Sonia Gandhi who will take the final call on the ruling UPA's candidate. While Finance Minister Pranab Mukherjee has emerged as front-runner, there is no clarity on who would be the UPA's choice for the post.

As the tempo built up, the Congress let out little and only said that there were no differences amongst the allies. It is being hoped that the wait for the UPA's 'consensus' candidate ends on Wednesday when Trinamool Congress chief Mamata Banerjee meets UPA chairperson Sonia Gandhi. Mamata may also meet another crucial UPA ally, Samajwadi Party (SP) chief Mulayam Singh Yadav, on Wednesday.

Meanwhile, new names like Somnath Chaterjee and Mohsina Kidwai have emerged in the race. Given the uncertainty, the final name could well be a dark-horse. As specualtions and political machinations continue over the race to the Raisina Hill, CNN-IBN brings you a reality check on where the various political formations lie vis-a-vis the Presidential elections.
