While the claim may be ridiculous, and the evidence for it never forthcoming, it is probably fair to say that she paints what she sees.

Take a look at this:

http://www.montgomerycountymd.gov/Elections/Resources/Files/htm/2016/generalelection/results/Official%20Cumlative.HTM

This is the November election results of the Maryland County just north of DC. 74.72% for the losing presidential candidate.

You'll find similar results in Cook County, Illinois, the areas around San Francisco, Boston, New York City, and a number of others.

What do you think the local media reports?  What do you think fills the Boston Globe or the Washington Post?

Swimming in this sea of propaganda, surrounded by nodding heads wearing the same goggles you wear, how much objectivity do you think results?
