Hillary Clinton boasts big leads over Donald Trump in the key swing states of Colorado, Florida, North Carolina, and Virginia, according to a Wall Street Journal/NBC News/Marist poll released Friday. In Florida, which The Wall Street Journal described as the "nation's largest swing state," the presumptive Democratic nominee led Trump with 44 percent support to his 37 percent. Clinton led Trump 44 percent to 38 percent in North Carolina, 43 percent to 35 percent in Colorado, and 44 percent to 35 percent in Virginia.
The results in these states paint a much more promising picture for Clinton, compared to a previous Wall Street Journal/NBC News/Marist poll that found Clinton just barely leading Trump in Iowa and tying him in Ohio. That poll, however, came on the heels of FBI Director James Comey's announcement that Hillary Clinton's use of a personal email server during her tenure as secretary of state was "extremely careless."
The Wall Street Journal also notes that both Ohio and Iowa are among the less diverse states, and Clinton typically holds a big edge over Trump with non-white voters. Colorado, Florida, North Carolina, and Virginia, on the other hand, are "among the most racially diverse presidential battlegrounds, with large shares of Hispanic or African-American voters," The Wall Street Journal reports.
The latest poll was conducted from July 5 to July 11. The margin of error in the Colorado survey is plus or minus 3.5 percentage points. In Florida, North Carolina, and Virginia, it's plus or minus 3.3 percentage points.
