LUCKNOW: It had happened in west UP and now BSP chief Mayawati's worst fear is apparently coming true in the east as well. The breaking away of non-jatav dalits from the party and their perceptible gravitation towards the Bharatiya Janata Party has put Mayawati in direct confrontation with the saffron outfit.Despite her efforts, the drifting of the second layer of dalit voters - pasis, dhobis, valmikis, khatiqs and dushads - to BJP is quite obvious. They may not be going en bloc, but a section is certainly opting for the saffron party as an alternative. "Communal polarization, of course, is one reason for this. But this is also happening because of the alienation of these castes which account for 45% of dalit voters," an observer said.Jatavs, the "creamy layer", who account for 55% of the total dalit population, are still staunch Maya supporters. Also called Chamars, they are the ones who have seen maximum progress during her rule while others have remained virtually untouched. This is the reason for a collective disenchantment among non-Jatavs.Political observers feel this is the reason Mayawati, who often ignores political barbs, is now reacting sharply, especially when BJP's Prime Minister pick Narendra Modi plays the caste card.On Friday, she called a news conference just to announce that she won't have any truck with a BJP-led alliance after the results."Earlier, when she spoke against BJP, it was primarily to assure Muslims that she would never side with the saffron party, hoping a big chunk of minority voters, apparently unhappy with Samajwadi Party, would consider BSP as an option. But now her rants against BJP is aimed at cautioning dalits - BSP's core voters - against falling into the saffron party's trap," a political analyst said.This frontal attack became even more essential for Maya when she came to know about BJP's ploy of telling dalit voters in the west that if they supported BJP in the Lok Sabha elections, the party would help Behenji in the state polls three years from now.So, rally after rally, she has been cautioning dalits not to get swayed by BJP's machinations. Her reaction got even more shrill when Modi in his eastern UP rallies suddenly pulled out the caste card and started projecting himself as a backward leader. "Is it a sin to be born in a low caste (neech)?" he said in Domariyanganj, in a reaction to Priyanka Gandhi's remark that he (Modi) indulged in "neech rajniti (low-level politics)".The retort to Modi's question, however, came not from Congress but from Behenji, who dared Modi to reveal his caste and called upon dalits not to get influenced by his low-caste avatar as a new 'messiah' of the downtrodden.
