Donald Trump may be having a comfortable lead over his intra-Party rivals, but he can't rest on his laurels judging the latest poll in Michigan.

Trump and Clinton are still leading by a good margin over their respective opponents, but both Clinton and Sanders have the upper hand in the general election contest, according to the NBC/WSJ/Marist poll. Clinton outpaces Trump 52 percent to 36 percent, while Sanders has it at 56 percent against Trump's 34 percent.

The NBC/WSJ/Marist poll was done from the period of March 1 to March 3. It involves more than 2,200 registered voters, 546 potential Democratic primary voters and 482 potential Republican primary voters. The polling period was conducted before and after retired neurosurgeon Ben Carson decided to drop out of the GOP's presidential nomination bid.

The GOP Numbers

The results of the poll in the GOP side showed the numbers heavily in favor of the real estate tycoon. He registered a 40 percent vote while Ted Cruz had 19 percent followed by Marco Rubio with 15 percent and John Kasich with 11 percent. Carson, meanwhile, had 9 percent at the last spot.

Breaking down the numbers, Trump has gotten the support of the majority from various demographic groups such as men, women, Republicans, independents, moderate GOP primary voters and conservatives.

Surprisingly, he also scored a slim margin over Cruz from the white evangelicals with his 30 percent compared to Cruz's 29 percent. Meanwhile, Cruz, as expected, secured the votes from "very conservative" GOP primary voters with 43 percent for him against Trump's 30 percent.

Rubio, on the other hand, lagged behind Trump and Cruz in the Michigan poll. While John Kasich only made it as far as the fourth, he is still hoping that the tides would turn for his favor.

According to the American Research Group, Kasich will finally make it on top and overtake frontrunner Trump. However, he better not get his hopes up too high and take the poll with a little grain of salt as the other polls show that the chances isn't as good as what he is hoping for.

Over at the Other Side

On the other hand, the 2016 Presidential Nomination: Battleground Tracker from CBS News showed that Hillary Clinton still has a comfortable lead over her counterpart Bernie Sanders. She scored 55 percent of the votes as compared to Sanders 44 percent.

The CBS News 2016 Battleground Tracker is a panel study involving 1,415 interviews of Michigan's registered voters. The interviews were done online by online polling group YouGov. The numbers reflect that of the NBC/WSJ/Marist that show Clinton leading Sanders by 17 points among primary voters.
