The newly released Wall Street Journal/NBC News/Marist poll shows the two party frontrunners with wide leads in Michigan, which is set to hold primary elections on Tuesday. The survey found that 41% of likely Republican primary voters chose Trump as their first choice candidate, 19 points ahead of Texas Sen. Ted Cruz, who came in at 22%. Florida Sen. Marco Rubio comes in third with 17% followed by Ohio Gov. John Kasich at 13%.

Clinton is leading Vermont Sen. Bernie Sanders 57% to 40% among likely Democratic primary voters, and both would beat Donald Trump in a head-to-head match. Clinton leads the Republican frontrunner by 16%, and Sanders by 22%.

The survey was conducted over a period of three days ending on March 3, when Michigan native Mitt Romney gave a scathing speech about Trump, calling him a “phony” and a “fraud.” The following day, Dr. Ben Carson, also from Michigan, announced that he was ending his campaign, though it had a minimal effect on the poll’s outcome. His 9% was distributed among voters’ second-choice candidates, spread out fairly evenly.

This poll follows Super Saturday, during which Cruz won two out of four states with a wide lead over Trump, who won the other two by narrow margins.
