Hillary Clinton leads Donald Trump by six points in the battleground state of Wisconsin, according to a new Marquette Law School poll of likely voters.

Forty-six percent of respondents said they support Hillary Clinton and 40 percent support Donald Trump. Libertarian Gary Johnson sits at four percent and Green Party candidate Jill Stein is at three.

The poll also found a tightening Senate race between Democrat Russ Feingold (45 percent) and incumbent Republican Sen. Ron Johnson (44 percent).

Recent battleground state polling has shown Clinton’s lead over Trump narrowing, though the NBC News battleground map shows the Democrat still has more than the 270 electoral votes needed to clinch the White House.
