There's headlines every day from Labour people saying don't vote Labour, Conservative people saying don't vote Conservative, Brexit party people saying don't vote Brexit party. Including some candidates who are standing themselves! and former prime ministers! 
It's like the more they know about the inside info on their parties the more afraid they are of them being in power. And all the reasonable individuals seem to have left politics or be lying low.
With tactical voting even Liberal Democratic and Green people saying don't vote for us.
How the hell is the woman on the street supposed to choose how to vote.
