Hillary Clinton holds an average 5.2 point lead over Donald Trump in a poll of 11 key battleground states. According to Politico, Clinton tops Trump 45.2 to 40 percent in a weighted poll based on the averages of surveys conducted by several well-known polling outlets, among them Quinnipiac, NBC/Wall Street Journal/Marist, Monmouth, CBS News/YouGov, Suffolk University, The Washington Post, Marquette Law School, Bloomberg, Fox News, CNN/ORC and Public Policy Polling.

Trump's Latino Struggles

A recent Univision poll of Latino voters in Arizona, Colorado, Florida and Nevada found Clinton besting Trump by an average of 41 points. Here biggest lead is in Arizona, where she leads by a margin of 68 percent to 18 percent and her smallest is in Florida, where she has a 24 point edge.

Trump marked the launch of his campaign by deriding Mexicans as "rapists" and criminals and has vowed to deport millions of undocumented immigrants "within his first hour in office."

More recently, he has sought to walk back some of his more explosive vows, now insisting that the deportation efforts will be targeted on immigrants without legal status who have criminal records.

Following a speech on immigration last month in Philadelphia, where he largely stuck to some of his more hard-line stances, several members of his Hispanic advisory council publicly withdrew their support of him.
