(CNN) Former Vice President Joe Biden leads President Donald Trump in head-to-head matchups in the crucial battleground states of Michigan and Pennsylvania, according to new Fox polls released Wednesday.

Almost half of registered voters in Michigan (49%) plan to support Biden versus 41% who say they'll vote for Trump, the polls showed.

And the numbers are relatively similar in Pennsylvania, where Biden leads Trump by 8 percentage points, with 50% of registered voters planning to vote for the former vice president to 42% for Trump, according to the new Fox News polls.

Fox's last national poll in early April found Trump and Biden even among registered voters.

The higher numbers for Biden come at the same time as the coronavirus pandemic, which has caused multiple states to delay their primaries.
