How much did Putin spend on his election campaign? | Vestnik Kavkaza

Putin will have no problem financing a campaign (as if he even needs to campaign...), he would have called up all the oligarchs together

and they would give him all the money he wants...

Love the Ekaterininsky Hall of the Kremlin, btw. That's where the Imperial Senate sat, before the Bolshevik Revolution. That's why that building is also called the Senate Building...
