A Monmouth University survey
of likely voters shows Clinton's lead is 43% to Trump's 38% -- with 7% backing Libertarian Gary Johnson and 3% supporting Green Party nominee Jill Stein.
And a Marquette University Law School poll
finds Clinton's lead with likely voters is 45% to Trump's 42%. In a four-way matchup, it's 37% Clinton, 32% Trump, 11% Johnson, 7% Stein and 13% undecided.
Those results are much tighter than the findings from the last Marquette poll in early August. That one found Clinton ahead by 15 points among likely voters.
What it means: Clinton's post-convention bump in Wisconsin is gone.
Trump's strongest spot is with white men, with whom he leads 51% to 29%, the Monmouth poll found. But he trails 50% to 33% among white women, and Clinton leads 67% to 12% among black, Hispanic and Asian voters.
"The current presidential election race in Wisconsin is looking a lot like the 2012 contest right now," said Patrick Murray, director of Monmouth University Polling Institute. That year, President Barack Obama defeated Mitt Romney, 53% to 46%.
Monmouth's survey included 404 likely Wisconsin voters. It was conducted August 27-30, with a margin of error of plus or minus 4.9 percentage points.
The Marquette Law poll included 650 likely voters. It was conducted August 25-28 and has a margin of error of plus or minus 5 points.
Both polls found good news for Democrats on the Senate front. Democratic challenger Russ Feingold leads Republican incumbent Sen. Ron Johnson, 54% to 41%, according to the Monmouth poll. The Marquette Law result was tighter, showing Feingold leading Johnson, 48% to 45%, among likely voters.
