The issue was quickly remedied, but not before the internet screenshotted their jokes:
The nation's first polls close at 7 p.m. EST.
To quote the great 2000 movie "Almost Famous," it's all happening. The lengthy and turbulent general election cycle was finally drawing Tuesday to a close as thousands of people headed to their local polling places and cast ballots for their candidates of choice.
The big decision, of course, was between Republican nominee Donald Trump and Democratic candidate Hillary Clinton. Both widely unpopular, the two politicians each had their share of scandals. He had a leaked audio tape in which he used profanity to describe sexually assaulting women; she had the use of a private email server while secretary of state.
Heading into Tuesday's election, Clinton was leading ever so slightly. According to the RealClearPolitics average of national polls, the Democrat was polling at 45.5 percent to Trump's 42.3 percent. Libertarian candidate Gary Johnson and Green Party nominee Jill Stein trailed the two major candidates at 4.7 percent and 1.8 percent, respectively.
As of Monday afternoon, the data site FiveThirtyEight gave Clinton a roughly 70 percent chance of winning the election, scoring swing states like Florida, Colorado, Nevada, North Carolina and Pennsylvania in her favor. Trump, however, was projected to win Ohio.
"In the prognostication business, what you predict at the end — when the drift of the year is usually fairly clear — is less significant than what you predict months before, at a time when the future is foggy," University of Virginia politics expert Larry Sabato and his staff wrote in a Monday newsletter. "Starting in March, we have released a total of 17 electoral college maps in the Clinton-Trump race. Not even on Clinton’s worst campaign days did we ever have her below 270 electoral votes."
Early voting turnout numbers in several states exceeded their 2012 levels. In the last general election, about 58 percent of eligible voters turned out to cast ballots, down from 62 percent in 2008, according to the Bipartisan Policy Center. That, of course, was also a historic election — the nation's first black president, whereas Clinton could be the country's first female commander-in-chief.
