If you have a "soccer mom" appearance you might also be a target of harassment:
"A Donald Trump supporter carrying a gun and passing out sample Republican literature in front of a Virginia polling site badgered a mom with her young son as she attempted to cast her vote but police declined to intervene because of the state’s open carry laws, she claimed." http://www.nydailynews.com/news/politics/armed-man-donald-trump-shirt-harasses-va-mom-polling-site-article-1.2859605
Note that in VA, as in many states open carry is not permitted on school property. She was voting at a county office.
Source of "Vote Early and Often"
The cynical phrases "Vote early -- and often" and "Vote early -- and vote often" are variously attributed to three different Chicagoans: Al Capone, the famous gangster; Richard J. Daley, mayor from 1955 to 1976; and William Hale Thompson, mayor from 1915-1923 and 1931-1935. All three were notorious for their corruption and their manipulation of the democratic process. It is most likely that Thompson invented the phrase, and Capone and Daley later repeated it.
