Hillary Clinton has widened her lead over Donald Trump in Ohio and is now beating the GOP nominee by six points, according to a CBS News poll released Sunday.

With a lead of 46 percent to Trump's 40, Clinton's good fortune in the critical battleground state is actually up from June, when she was ahead of the billionaire businessman by four points.

In Iowa, another big swing state, Clinton and Trump are tied at 40 percent.

Clinton has gained with women, and she continues to enjoy a virtually unified front from Democratic voters, polling data found.

Trump, on the other hand, still struggles with Republican infighting, as opposition among some conservatives to his candidacy has yet to subside.

Where Clinton has 90 percent of Democrats, Trump's support from Republicans registers at around 79 percent, CBS News found.

"The poll asked people what it would take to get them to reconsider Trump if they aren't currently voting for him. While there aren't a lot of people who said that anything could make them rethink the contest — fewer than one in five — there are enough people that Trump could potentially make some inroads," CBS explained.

It added, "Their top answer is that Trump convinces them he is 'prepared to be commander-in-chief.' ... [Seventeen] percent of those not with him might reconsider if he 'apologizes to people he has offended' — though that sets up a balancing act for him because other recent polls have suggested his current supporters would not see any such needs."

Trump last week expressed "regret" for some of his remarks.

The surveys, which was conducted from Aug. 17-19, also showed one of the chief things hurting Trump right now is that he is seen as a "risky" candidate.

"That is especially the case among women. In Ohio, 73 percent of women describe him as such, and 70 percent of voters overall," CBS reported.

It's also important to note that the survey, which has a margin of error of plus or minus four percentage points, showed some problems for Clinton, namely, that she is not viewed in Ohio as "looking out for people like you."

Fewer than 44 percent of survey respondents said they think the Democratic candidate is looking out for them, "which also connects to voters' doubts about her truthfulness, and to the fact that many voters feel she is too connected to the influence of foreign donors," the report noted.
