According to reports I had recently seen following the snap election, the tories only mustered around 28% of the nonwhite vote in the UK.
That is either just as poor as or only marginally better than the GOP performance in recent years.
The tories are also much more leftwing than the GOP- on healthcare, welfare, childcare, education, etc.
If the tories can't make inroads with ethnic minorities in the UK, then how can the GOP?
Trump got around 21% of the non-white vote in 2016 so 28% isn't bad for the Tories I don't think.
