I'm in a similar position to you and millions of others, I've been labour all of my life but voted UKIP the last couple of GEs, except last year when I chose not to vote. I just can't vote for Labour with Corbyn and Abbot at the helm, also my local MP, Alan Whitehead has been calling for another referendum on Europe!
I am against everything that the Tories stand for, May is full of broken promises and bullsh!t and the in fighting is incomprehensible!
Lib Dems are a big no no for me, Cable is a dinosaur and people still remember Clegg giving up all his principles for a bit of power!
So where does that leave voters like me, I truly believe that big changes need to be made in ALL of the parties, root and branch clear outs, get some young blood at the head of all 3 main parties, the same old cronies have had their day, time for change is NOW!!
