Hillary Clinton is making a strong push for Nevada, including it in her campaign's $7 million battleground state ad blitz last month, but a new poll finds Donald Trump catching up to her in the Silver State.

According to the latest Monmouth University poll, Clinton leads Trump 45 to 41 percent among likely general-election voters in Nevada, putting the presumptive Republican presidential nominee within the poll's 4.9 percentage point margin of error against her.

Libertarian Party nominee Gary Johnson secures 5 percent support and 4 percent of Nevadans signaled they will choose their state's "none of these candidates" option on the ballot in November.

Clinton garners slightly more support from members of her own party. Ninety-two percent of Nevada Democrats intend to vote for the former secretary of state, while 3 percent plan to support Trump. On the Republican side, 88 percent support the billionaire and 6 percent plan to back Clinton.

Trump leads Clinton 39 to 37 percent among independents in the battleground state in addition to carrying an edge among men (44-37) and white voters (49-37). He is led by Clinton among women (53-38) and minorities (64-23).

Both candidates maintain net-negative favorability ratings. Fifty-four percent of voters hold an unfavorable view of Clinton, while 53 percent view Trump negatively.

Unlikely to help Clinton's image among Nevada voters is the FBI's recent decision to not recommend criminal charges against her. Forty-four percent believe the former first lady acted criminally in her handling of classified material at the State Department, not including 27 percent who said her actions demonstrate "poor judgement." Only 13 percent of Nevadans said Clinton did nothing wrong, while 16 declined to give an opinion.

The Monmouth University poll of 408 registered voters in Nevada was conducted between July 7-10.
