Perhaps the BJP's conquest of the North East nudged both Yadav and Mayawati into a reality check: that they would have to bury the animosity of 23 years the last time the two parties allied and formed the government in UP in 1993 or risk political oblivion as the BJP grabs large chunks of their respective vote banks. The BJP can also bank upon the charisma of Modi and Yogi currently being projected by the party as a pan Indian "Hindutva icon" to continue its winning streak across UP.

The BJP has morphed from being considered a largely upper caste party in UP to being a magnet for all castes. The RSS and Modi have steadily tried to co-opt Dr BR Ambedkar into the Sangh pantheon and this has paid dividends among Dalit voters. Separately, the upper castes are thrilled that Adityanath, a Thakur, is Chief Minister, though as a Yogi (monk), he has no caste (having given up the trappings of caste according to traditional Hindu beliefs after becoming a monk) as the BJP projects.

Mayawati was characteristically blunt while announcing the tie-up with Akhileh Yadav, describing the strategy as "ek haat le, doosre haat de" (you have to give a little, take a little). The experiment hopes to move her voters towards Yadav Junior who calls her "bua" (aunt) for the by-elections; in return, he will help her win one of the 10 Rajya Sabha seats that will be decided later this month (the BJP is certain to win eight).

Mayawati has only 17 votes in the state assembly; the Samajwadi Party has 46
Mayawati has also managed to get the Congress to support her Rajya Sabha candidate in exchange for supporting the Congress' choice in Madhya Pradesh for the Upper House.
Congress President Rahul Gandhi had decided to go and meet his grandmother in Italy when the news of the North East defeat came in last week. This would have been familiar to erstwhile ally Yadav, who last year had to address a press conference solo after the Congress-SP combo failed miserably in the Uttar Pradesh state election.

But the Congress is in no position to call the shots. It needs to act as a catalyst of a grand UP alliance to take on the BJP, similar to what the opposition managed to achieve in Bihar when Nitish Kumar and Lalu Yadav came together in 2015 in a "Maha-gatbandhan" brokered by the Congress. The BJP was defeated.
If the SP and BSP succeed in winning Phulpur, then the alliance will look urgent and attractive and will also ensure that the Congress plays ball. Gorakhpur, however, is pretty much a Yogi fiefdom and he is ensuring with his non-stop campaign that it remains with the BJP as it has from 1991.
So it is the Phulpur result which will indicate what next for the most politically strategic state in the country. In some ways, it is even more of a bellwether than the Karnataka polls. Results will be known on March 14.
