Updated

Democrats hold single-digit leads in the key Senate contests of Colorado and Michigan, as well as in Colorado’s gubernatorial race, according to new NBC News/Marist polls of these two states.

But with less than four months to go until Election Day, Republicans are narrowly ahead in the race for Michigan governor.

Dems 'doing well' in battlegrounds: poll

Top Talkers: Colorado Democratic Sen. Mark Udall is beating his challenger, Cory Gardner, according to a new NBC News/Marist poll. And in Michigan, Rep. Gary Peters is leading his GOP challenger. But the poll also shows a silver lining for the GOP. The…

In Colorado’s Senate contest, incumbent Sen. Mark Udall, a Colorado Democrat, leads GOP challenger Cory Gardner by seven points among registered voters, 48 to 41%; another 10% are undecided.

In the state’s race for governor, sitting Gov. John Hickenlooper holds a six-point edge over Republican opponent Bob Beauprez, 49% to 43%, with 7% undecided.

Meanwhile, in Michigan’s Senate contest, Democratic Rep. Gary Peters is ahead of Republican Terri Lynn Land by six points among registered, 43% to 37%.

“The early edge goes to the Democrats” in these Senate match ups, says Lee Miringoff, the director of the Marist College Institute for Public Opinion. “But these are not states they can put into their win column just yet.”

And in the Wolverine State’s gubernatorial race, incumbent Republican Gov. Rick Snyder holds on to a two-point over Democratic nominee Mark Schauer, 46% to 44%, although that’s within the survey’s margin of error.

“The Republican governor is holding his own so far,” Miringoff adds.

Helping Democrats: The gender gap, Latinos and independents

A gender gap is helping the Democratic candidates in these two states. In Colorado, Udall is up by 12 points among female voters (50% to 38%), but he’s running neck and neck with Gardner among men. And in Michigan, Peters is ahead by 13 points with women (46% to 33%).

Among Latinos – who make up 16% of registered voters in the Colorado poll – Udall has a 31-point lead over Gardner, 58% to 27%.

And also in Colorado, both Udall (by 50% to 34%) and Hickenlooper (by 52% to 35% have the advantage with independent voters.

By contrast, in Michigan, Gov. Snyder holds a 14-point edge among independents – which explains his narrow lead in this Democratic-leaning state.

“Democrats’ strength is women, and Republicans’ strength is health care”

Snyder’s job-approval rating among Michigan voters is 49%, while Hickenlooper’s in Colorado is 54%.

Helping Republicans: Disapproval of the health-care law, Obama

Yet what’s helping Republicans in these two states is a negative attitude about the 2010 health care law.

In Colorado, 52% of voters view the law as a bad idea – including 46% who hold that position strongly. That’s compared with just 37% who believe the law is a good idea.

Michigan voters think similarly – 50% see it as a bad idea, 32% a good idea.

“Democrats’ strength is women, and Republicans’ strength is health care,” says Marist pollster Barbara Carvalho.

President Obama also is unpopular in these two states he carried in the 2008 and 2012 presidential races: In both, just 40% of registered voters approve of his job.

However, just 19% of Michigan voters and 21% of Colorado voters approve of the job congressional Republicans are doing.

Divides on immigration, global warming

Registered voters in both states are divided about a move to reduce greenhouse gases, even if it means higher utility bills for consumers. Forty-five percent of Michigan voters said they approve of such a proposal, versus 47% who said they disapprove. Coloradoans were slightly more in favor of the proposal to reduce global warming; half of voters said they approve of the move, compared with 40% who said they disapprove.

The poll showed a wider divide between the two states on the issue of immigration. In Colorado, where Latinos made up 16% of registered voters, 56% said they favor giving undocumented immigrants a pathway to citizenship, while 40% oppose that measure. But in Michigan, where Latinos only make up 3% of registered voters, only 47% back offering the opportunity for citizenship, while 46% do not.

In Colorado, where Hickenlooper has taken heat for appearing to change his opinion on a controversial gun control measure, voters are deadlocked on the issue of rules involving the sale of firearms.

Among registered voters, 40% say they would be more likely to vote for a candidate who believes the sale of firearms should be less strict, while 52% say the opposite.

“In Colorado, on the gun control issue, there was a sentiment not to do much of anything. People don’t want to support someone who wants to limit [the laws], they don’t want someone who wants to weaken the restrictions,” said pollster Lee Miringoff. “It’s very polarized.”

Opposition to the loosening of gun regulations is largely fueled by female voters, who say they are less likely to support a pro-gun rights candidate by 20 percentage points, while men are about equally divided on the question.

But no equivalent gender gap exists on the issues of contraception and abortion, also controversies that are animating the state’s Senate race.

Only 16% of Coloradoan voters said they would be more likely to vote for a candidate who supports restrictions on the use of contraception, and just 25% said the same of a candidate who would restrict access to abortion.

The NBC/Marist poll of Colorado was conducted July 7-10 of 914 registered voters, and it has a margin of error of plus-minus 3.2 percentage point.

The NBC/Marist poll of Michigan was conducted July 7-10 of 870 registered voters, and it has a margin of error of plus-minus 3.3 percentage points.
