2018 Election Day: Americans are ready to vote in a historic contest, with the Trump presidency in the foreground

The race has been long – few people can attest – but the day of elections 2018 has finally arrived.

This year's midterm elections are the first national competitions since 2016, when President Donald Trump won a thwarted victory over former Secretary of State and Democratic candidate Hillary Clinton.

Many, including the president, see this election as a referendum on his term – something that Trump has adopted as he's been crossing the storm country in recent weeks.

"I'm not on the ticket, but I'm on the ticket because it's also a referendum on me," Trump said at a rally in Southaven, Missouri, in early October. "Imagine I'm on the ballot."

It is a refrain he repeated to try to take advantage of the popularity of his base to further strengthen the scope of the Republican Party, especially in rural areas, where blue-collar and white majority rule.

As Tuesday night approaches, Republicans not only control the White House, but also both Houses of Congress.

In the Senate, where elections are staggered and senators have a six-year term, 35 seats are available. In the House, where elections are held every two years, 435 seats remain.

Discussions of Democrat enthusiasm that could lead to a "blue wave" dominated the conversation.

Democrats seem more inclined to victory in the House, where they need a net gain of 23 seats to make up the majority. In the Senate, Democrats would need a net gain of two seats to take control, but 10 vulnerable Democrat senators show up in the states that Trump won in 2016.

Early voting has also been interpreted as a sign of growing enthusiasm, although in some states it is the result of new possibilities for early voting. According to the data of Michael McDonald, an advance voting expert at the University of Florida, 2018, the advance vote has already far exceeded the 2014 figures.

Friday, more than 30 million anticipated votes were cast. In 2014, the same day, 17 million ballot papers were cast. And the total number of advance polls in all of the 2010 interim sessions has risen to just over 19 million.

According to the latest ABC News / Washington Post poll, health care and the economy are at the heart of voters' concerns this year. The importance of voting choice is almost linked to that of immigration. Democrats have made health care – and especially coverage of people with pre-existing illness – a key part of their platform, while Trump has significantly beefed up his rhetoric about immigration, using a caravan located a few weeks from the frontier vanguard.

Despite strong partisan positions on these issues, election candidates across the country this year are varied and many are ready to enter history.

If elected, Democrat Stacey Abrams, Georgia's governorship candidate, will be the first female African-American governor in US history. Three other states south of the Mason-Dixon line could also elect their first African-American governor.

It could also be a historic year for Native American women. In the House, Sharice Davids of Kansas and Debra Haaland of New Mexico, both Democrats, could become the first women of Amerindian Congress. Paulette Jordan, a Democrat in search of the Governor of Iowa, could become the first Amerindian governor of the country, as well as the first female governor of that state – and the first Democratic governor of Idaho since 1999.

There are also two Muslim congressional candidates, Rashida Tlaib in Michigan and Ilhan Omar in Minnesota, who are also on the verge of making history.

And Vermont is about to mark the history of the LGBTQ community if voters in the state of Green Mountain upset their current governor for the benefit of the first candidate, Christine Hallquist, who would be the first transgender governor of the country if she were elected on Tuesday.

In some states, the two candidates on the ticket offer diverse and historical choices.

In New Hampshire, Eddie Edwards, a Republican might be the first African American member of Congress. His opponent, Democrat Chris Pappas, could be the first openly congressional congressman in Congress.

And although many more individual candidates could potentially be actors of historical change, taken together, there are also themes that break records.

Women, for example, run in numbers never seen before.

Today, 84 of the 435 members of the House are women, while on November 6, 239 women are eligible. They are former fighter pilots, intelligence officers, doctors, nurses and scientists. At a margin of 3 to 1, these candidates are also Democrats.

Veterans are also on the ballot in record numbers. According to a super PAC, a non-partisan veteran, more than 200 veterans would show up at Congress – an absurd figure if we consider that there are fewer veterans in Congress today. now, 20% more than before.

Polls in competitive races begin to close at 19 hours. EDT and continues until 1 hour EDT.

After months of fundraising, advertising, door-to-door and block, the candidates made themselves known.

Now, it's up to the voters.
