"Buoyed by a string of decisive primary wins this past Tuesday, both Hillary Clinton and Donald Trump hold a commanding lead in New York State, where a victory in the April 19 primary could effectively seal the presidential nomination for both candidates.
With Marco Rubio out of the race, Trump leads his closest rival, Texas Senator Ted Cruz, by 52 points (64% to 12%). Rubio received 4% of the vote before suspending his campaign. Ohio Governor John Kasich earned just 1%, getting no bounce from his recent home-field victory in the Buckeye State. In a hypothetical, two-man matchup between Trump and Cruz, Trump leads 69% to 25%."...
"Trump has the highest favorable ratings with GOP voters, 71%/23%, followed by Cruz at 52%/44% and Kasich at 54%/34%. Consistent with other primaries, Trump supporters are the most loyal, with 89% of those who see him favorably planning to cast their ballot for him. In contrast, only 21% of Republicans who have a favorable opinion of Cruz say they will vote for him."...
