Theresa may is on borrowed time, the last thing on her priority now is Immigrant.
The DUP are funny, they are more pragmatic on certain issues than the Tories, and this may be the case because Northern Ireland is not as Hostile on Immigration as in England.
The DUP are indeed extremist, the whole history of the DUP is built on Extremism, bigoted tendency, discrimination ,misogyny and Homophobia. However when it comes to unskilled and skilled migration,they do take a pragmatic view, in that they do support it to meet the economic needs of Northern Ireland.
The want an open border with Northern Ireland, they support smooth trade. Their policy tend to align more towards continued membership of the custom union. Their position on the single market is a bit unclear.
Judge not, and you will not be judged.
