CHENNAI: The long suspense over whether Rajinikanth would enter politics finally ended today,(Dec.31) with the superstar making the announcement amid frenzied cheers of hundreds of supporters. "I will do my duty... it is time. We will change the system," the 67-year-old declared in Chennai, saying he would form a new party. Claiming that the events in Tamil Nadu over the last year have made the state a laughingstock, he said, "If I don't make this decision now... the guilt will haunt me". The death of AIADMK's iconic leader J Jayalalithaa last December is seen to have left a vacuum in the state's politics. The other big actor, Kamal Haasan, who announced his intention to enter politics last month, has congratulated Rajinikanth. NDTV
Rajnikanth’s chart is available at the reference  below. Notice that Mercury has just stationed direct conjunct the IC [14sa] of the chart. This is the position of a massive galactic anomaly called the Great Attractor (Abell 3627). The following edited extract from Philip Sedgwick’s article  explains how it works for an individual who has it prominent in his chart.
Should one hold strong GA connections, these attributes directly apply in the real world. Others make the assumption that GA people have something important to say. Ironically, once these people show what they know, others flock to them like flies to melting ice cream on a hot summer day. Simply and graciously, they receive the accolades rendered to their insight and knowing.
This certainly explains the huge mass following of Rajnikanth.

Kronos-Pluto: to be aware of the power of people in charge – and to see abuses of power through misuse of office, position, laws and procedures; to push for leadership or control. 
But let us first dwell on the potential of the newly discovered dwarf planet Haumea. About Haumea, Nick Fiorenza  writes:
Haumea supports a new birth in consciousness, or more so, aiding humanity's re-birth into a spiritually aware state of being. It would seem Haumea's driving intent is that to intercede in what the old totalitarian powers have repeatedly demonstrated throughout Earth's history—the repetitive destruction of the peoples of the Earth and inability to ensure a safe evolution and ascension of humanity.
Haumea's South Node in early sidereal Capricorn conjoining Altair of Aquila, and its North Node in sidereal Cancer conjoining Talitha, the fore-foot of the Great Bear, motivates us to move from self-interest-based covert and manipulative shenanigans to that of being a caring force supporting the nourishment and awakening of humanity. It also reveals the need for world powers to move from a power-hungry, authoritarian, tyrannical, militaristic focus toward one that creates a protective and nourishing environment from which humanity can awaken into a new light of being.
Having dwelt on Rajnikanth’s horoscope, let us now look let us look at the chart for the Pluto station direct on September 29, 2017 drawn for Madras (Chennai). As always what is brought to the angles should draw our attention. Here we have the Jupiter-Uranus opposition aligned with the meridian.
Jupiter is the great benefactor, the king of all gods, Jupiter magnifies and inflates everything it touches. Uranus is the rebel, the freedom-seeker, the reformer and the revolutionary. Together, the two stand for the faith and the courage to break free from the old and reinvent the new. Jupiter opposite Uranus is a very progressive aspect. Things are likely to happen in a BIG scale and impact society as a whole.
In 1989 when we had the Jupiter Uranus oppposition on the Cancer Capricorn axis, the Berlin wall and the Communism collapsed and the Cold War was declared over. South Africa’s new prime minister F.W. de Klerk started to dismantle the apartheid regime.
In 2003 when we had again a Jupiter Uranus opposition this time on the Virgo Pisces axis, the US space shuttle Colombia crashed, and the U.S. and Britain launched the war against Iraq.
If we look back in time when we had this transit we notice some common themes: profound changes in societal structures, taking a stand, restlessness, revolutions, techonological progress, scientific discoveries. https://astrobutterfly.com/2016/12/24/jupiter-opposite-uranus-a-cosmic-high-five/
If now we progress the chart to December 31, the date of the news, we find that the Jupiter-Uranus opposition that was aligned with the meridian is now reaching a conjunction to the progressed horizon – a clear indication that it is being activated. Also, Uranus stations direct on Jan.2 on the MC kick starting the opposition.
With Jupiter-Uranus, the tendency to totally renew and start afresh. This is what Rajnikanth is attempting in Tamil Nadu politics. We can only hope that he will live up to the potential of the newly discovered planet Haumea, which is so significantly placed in his chart.
