That's a peninsula, not an island. An island is totally surrounded by water, but a peninsula is mostly surrounded by water and connected to the mainland on one side.
In 2014, Raila Odinga went to the US for three months.
Upon his return, supporters organically mobilised themselves and went to receive him at the airport and accompanied him to Uhuru Park where he addressed a crowd of 1 million supporters.
Gachagua is trying to relive that glory.
Unfortunately, he's Gachagua and not Raila Odinga. He's an amateur.
His sparkless politicians have resorted to mobilising goons from the Kiandutu and Majengo slums in Nyeri to go and receive Gachagua at the airport or else he will deny them the DCP Party ticket.
