It seems our Constituency is neither a Lib Dem nor a Labour target seat, if we're splitting hairs.
Vote for whichever party you want, unbound by people telling you who to 'tactically' vote for - people who don't actually give a damn about lack of democratic process and corruption.
They don't know better than you, they're not your 'betters'.
Be curious. Do your own research. Make up your own mind. Be your own person.
