U.S. President Donald Trump's aggressive campaign to deport immigrants could weigh on his Republican Party in November's midterm congressional elections, a Reuters/Ipsos poll has found.

Some 52% of Americans in the six-day poll completed Monday said they were less likely to support a candidate who backs Trump's approach to deportations, significantly more than the 42% who said they were more likely to support such a candidate.

The disadvantage for Trump allies was more stark among people who don't identify with either major political party, with ?57% ?of independents saying they prefer a candidate who opposes Trump's deportations and 32% preferring candidates who support Trump the issue.?
