The first two phases of polling in western Uttar Pradesh will decide the electoral fortune of several lesser known political parties representing certain castes and sub-castes whose votes become crucial in cow belt politics.

These parties are hitherto less known in the country's political spectrum, but come elections they play a key role as they can decide the prospect of a candidate, especially this time when the stakes are very high.

Some of the leaders, who have named their parties after their castes to garner votes, have termed big political parties as 'bahri' (outsider).

Some of these caste-based parties are also testing their popularity in eastern Uttar Pradesh, seeking to extend their territory.

Mahila Shashtkikaran Party leaders are raising the issue of women safety which is most talked about in western parts of the state, while Brij Kranti Dal leaders plan to cash in on the sentiments related to Brij Land history and are being seen to have popular acceptance in districts like Mathura and adjoining areas.

While Bhartiya Kisan Union (BKU) is not in the fray this time, there are a number of small parties championing the cause of farmers and helping big parties to garner votes by highlighting their farm policies and promises.

Outfits like Bhartiya Vanchit Samaj Party, Bhartiya Karyastha Sena, Kisan Mazdoor Suraksha Party and Bhartiya Bhaichara Party are toiling hard to make their presence on the state's electoral map.

These parties mostly harp on issues related to the downtrodden sections of the society. Some of these came into existence post Muzaffarnagar riots and talk about communal harmony.

While the first of seven-phase polling for 73 seats in 15 districts is over, the second phase of polling on February 15 will cover 67 seats in 11 districts – all in western Uttar Pradesh.

Outfits like little-known Suheldev Bhartiya Samaj Party or Janwadi Party (Socialist), headed by Sanjay Singh Chauhan, matter for mainstream political parties like BJP and Congress because of the support they enjoy among certain castes.

The Paschimi Uttar Pradesh Vikas Party is raising the issues that have not been touched upon by major parties.

Apna Dal headed by Union minister Anupriya Patel is already an NDA ally, is contesting some 10 seats in western UP though it did not win a single seat in the belt last time.

Seeking to leave their mark in state politics, Peace Party, Nishad Party and Mahan Dal are also in the fray.

OBCs are roughly 44 per cent of UP's electorate, Dalits 21 per cent, Muslims 19 per cent, and upper castes 16 per cent. Yadavs, the core of the SP's base, are numerically and socially dominant among OBCs.

But the 200-odd non-Yadav OBCs together account for over double the Yadav population. They include Kurmis, Koeris, Lodhs, Jats and Sunars, while Pasis and Valmikis are the large groups among Dalits.
