The 2020 presidential election will be the last presidential election held under the Democratic Party’s “blue wall” electoral firewall, a strategy that will help to elect Democratic presidents and reduce the chances of a Republican victory.

The blue wall is designed to prevent the Democrats from gaining enough seats in the House and Senate to hold a majority in both chambers of Congress.

It prevents a Republican from gaining a supermajority in either chamber.

It’s the third time in four years that Democrats have used the blue wall to hold onto power.

In 2010, they held a 52-seat majority in the Senate and won a majority of governorships and state legislatures.

And in 2014, they won a super majority in governorships in 10 states.

The new strategy will be different this time around, however, because of the dramatic shift in the demographics of the country.

In the 2016 presidential election, Democratic voters turned out in droves in key battleground states such as Virginia and Florida, and in battleground states like Colorado and Iowa, according to a new Pew Research Center analysis of Census Bureau data.

The demographic shifts that occurred in 2016 have left Republicans with a slight edge in the 2018 midterm elections.

But they’re still not expected to be enough to overcome Democratic gains in governors’ races, state legislative chambers, and state legislative seats in Congress, the Pew analysis shows.

The 2018 midterms also marked a pivotal moment in the country’s political evolution.

Republican President Donald Trump won the presidential election with more support than Democratic President Barack Obama.

The Pew analysis, based on a study of party registration data from the Federal Election Commission, found that in 2020, a majority (53 percent) of Americans who were registered as Democrats and unaffiliated with a political party voted for Hillary Clinton.

The percentage who voted for Donald Trump dropped from 54 percent in 2020 to 37 percent in 2021.

And in 2020 Republican voter turnout in battleground state contests dropped from 53 percent to 29 percent.

That’s a clear indication that Republicans have a much more difficult time convincing more moderate and minority voters to turn out for the party.

The analysis also found that the Democratic base is more educated, and that more women vote.

In 2018, 56 percent of all eligible voters were women, compared to 60 percent in 2019 and 65 percent in 2022.

Women are more likely to be registered as independent, according the analysis.
