Hillary Clinton leads Donald Trump in Iowa and Pennsylvania, while the two are tied in the key battleground state of Ohio, according to a trio of new NBC News/Wall Street Journal/Marist polls.
The two candidates are tied at 39 percent each in the Buckeye State. In March, Clinton held a six-point lead over Trump in the state — 48 percent to 42 percent.
In Iowa, the presumptive Democratic nominee is ahead of Trump by three points among registered voters, 42 percent to 39 percent, which is within the poll's margin of error of plus-minus 3.4 percentage points while a combined 18 percent say neither, other or undecided. In January, Clinton held an eight-point advantage over Trump.
In Pennsylvania, she leads the presumptive GOP nominee by nine points, 45 percent to 36 percent, with 19 percent saying neither or undecided. In April, it was Clinton 54 percent, Trump 39 percent.
