Bernie Sanders has narrowed Hillary Clinton’s lead in Wisconsin, according a Marquette Law School poll of voters who say they will vote in the state's Democratic primary released Thursday.

The former secretary of state’s 9-point lead over Sanders has dwindled to just 2 points — 45 percent to 43 percent. In Marquette Law’s November survey, Clinton led with 50 percent support to Sanders’ 41 percent. Former Maryland Gov. Martin O’Malley has dropped from 2 percent to 1 percent. (Contrary to the most current survey, respondents in November’s poll were asked questions regardless of their intent to vote in the April 5 primary.)


An overwhelming 65 percent see Clinton winning the Democratic nomination compared to just 27 percent for Sanders.

In the Republican results, Donald Trump overtook Ben Carson, who held a narrow lead over the field in November. The billionaire businessman garnered 24 percent support among Republican voters who plan to vote in the primary. Florida Sen. Marco Rubio follows with 18 percent and Texas Sen. Ted Cruz earned 16 percent. Carson sits at 8 percent, while the remaining candidates are at 5 percent or less.

Nearly half—49 percent—said they believed Trump is most likely to win the Republican nomination. Twenty percent said Cruz would win and 10 percent said Rubio.

In a general-election match-up, Sanders beats Trump, Rubio and Cruz by double digits. Clinton did not fare as well but still holds a 1-point advantage over Rubio and Cruz. And against Trump, she leads by 9 percentage points.

The survey of 312 likely Democratic voters and 313 likely Republican voters was conducted from Jan. 21-24 via cellphones and landlines. The margin of error for both groups is plus or minus 6.5 percentage points.
