Donald Trump and Hillary Clinton enjoy the support of roughly half of likely Connecticut primary voters in their respective parties, according to the results of the latest Quinnipiac University poll released Wednesday.

Trump's level of support among likely Republican voters is 48 percent, outperforming by 20 points his nearest competitor, Ohio Gov. John Kasich, who earned 28 points. Texas Sen. Ted Cruz finished a distant third with 19 percent and 5 percent undecided.


The results, which come hours after the Manhattan real-estate magnate scored a resounding victory in his home-state New York primary, show wide support for Trump among nearly all demographic and ideological groups. Kasich leads Trump by seven points among voters between the ages of 18 and 44.

Overall, three in four (74 percent) of Republican voters said they have made up their mind, while the remaining quarter said they could change the candidate they support. The share of certainty rises to 80 percent among likely Trump and Kasich voters, while roughly only half of Cruz's supporters said they are firmly committed to voting for him next Tuesday.

On the Democratic side of the race, Clinton leads Bernie Sanders 51 percent to 42 percent, with another 6 percent undecided. While Sanders leads by 11 points among voters describing themselves as very liberal, Clinton holds advantages among those who said they are somewhat liberal, moderate or conservative.

Sanders holds a 47-point edge over Clinton among voters surveyed between the ages of 18 and 34 and is even with Clinton among white voters, but the former secretary of state enjoys a 41-point lead with African-American voters.

Regardless of whom they supported, 40 percent said they would be very satisfied with Clinton as the Democratic nominee, while 31 percent said they would be somewhat satisfied. By comparison, 35 percent each said they would feel the same if Sanders became the Democrats' standard-bearer in November.

About eight in 10 likely Democratic voters said they have decided on their candidate, while around two in 10 for each candidate said they could change their mind.

Quinnipiac conducted the survey via landlines and cellphones from April 12-18, polling 823 likely Republican primary voters with a margin of error of plus or minus 3.4 percentage points, and 1,037 likely Democratic primary voters with a margin of error of plus or minus 3 percentage points.
