Fiona Patten looms as one of the biggest names to surrender a spot in the Victorian Parliament following Saturday night's state election, with the Reason Party founder firing a shot at the so-called "preference whisperer" Glenn Druery on her way out.

Ms Patten, who entered the Legislative Council at the 2014 election as a member of the then-called Sex Party, is likely to be squeezed out of the Northern Metropolitan Region in place of Derryn Hinch Justice Party candidate Carmela Dagiandis.

With just over 40 per cent of ballots counted, Ms Patten had received about 4000 more votes than the Derryn Hinch Justice Party in the Northern Metropolitan Region, however complex preference deals orchestrated by Mr Druery for Mr Hinch's party meant Ms Patten was destined for the exit door.

When people don't vote "below the line" on Legislative Council ballots, preferences are handed out according to the wishes of the party they cast their single vote for.
