They just need to fool enough of the people for enough of the time to gain power.
There are enough fuckwits whose only literate skill is the ability to write X next to reform on a ballot form.
Farage being led by the trumpian playbook. He'd sell the NHS to American operators in an instant, throw out pension guarantees, slash benefits. And all the fuckwits would wave a flag because a plane full of brown kids departed Stansted.
And they'd then complain when a GP visit costs £100, prescribed medicine costs £50, Grandma's pension will stay the same rate for five years. But don't worry, there's no car wash where an Afghan can touch the fiesta.
