Jim,
Ukip has always campaigned on a racist ticket - they took up where Powell
and B.N.P. left off

You make the claim but can not back it with a single fact.
Where is your evidence of racism?

By playing on people's Xenophobia, Brexit helped to swing the vote

Can you give an example of them doing that, or is it just another baseless smear?

There is no obvious increase in their popularity, no sign that they have made any grounds as a party,

Yes there is. Their vote has steadily increased.
In the general election Ukip came second in 118 of the 650 parliamentary seats.
They had more support than the Lib Dems and half Labour's vote.
"Overall, Ukip secured 12.6% of the vote, an increase of 9.5 percentage points from the 2010 election, the largest of any major party and more than three times the size of the SNP's improvement."

You'll be telling us your not an extremist next

I am not an extremist.
You will find no extreme view in any post of mine, but do try to prove me wrong.
