Among Republicans, Trump enjoys the most enthusiastic block of supporters. Seventy-one percent of his backers say they “strongly” support him, compared to 51 percent for Cruz and 44 percent for Kasich.

“We’re seeing in Maryland a similar pattern as we’re seeing elsewhere, with Trump in the low 40s and then Cruz and Kasich dividing up the rest,” said pollster Lee Miringoff. “Trump is well positioned because the other two are dividing up the pie.”
