There has been much talk about Trump having a ceiling, because his negatives are high. The Conservative Treehouse website reports the findings of a study done among North Carolina voters by the polling shop at Elon University.
They asked supporters of Carson, Cruz, Rubio, Bush, and Kasich who would be their second choice if their first choice dropped out. Unsurprisingly, Trump is the second choice of a lot of those supporters. He gets at least 29% of the supporters of each, and more in three cases.
This destroys the "Trump ceiling" narrative, doesn't it? It was always largely the product of wishful thinking. It appears he may be overcoming those high negatives.
Research shows that, at least in NC, The Donald would be the second choice of many of those for whom he is not a first choice. Go see the numbers for yourself.
