Democrats and the media have been trying to pinpoint the reason for Hillary Clinton’s downfall ever since Donald Trump defeated her in the November election.

They’ve blamed “fake news”, Russian hackers, and FBI Director James Comey.

But there’s one big reason she lost the election – and it’s remained a secret until now.

Donald Trump won the election by tearing down the so-called “Blue Wall”.

States like Michigan, Pennsylvania, and Wisconsin hadn’t voted Republican since the 1980’s.

But Trump flipped those states on his way to victory.

Many pundits wondered how he had turned the industrial Midwest red.

The answer is Right to Work legislation.

Right to Work ends the practice of compulsory unionism.

In non-right to work states, employees must pay union dues as a condition of employment.

Union bosses in turn take those dues and funnel billions of dollars into the accounts of Democrat politicians.

But Michigan and Wisconsin became Right to Work states in 2013 and 2015, respectively.

Wisconsin had also passed Act 10, which allowed public sector union members the option to not pay compulsory dues.

These pieces of legislation had a dramatic effect on union membership, which helped Trump win.

The Daily Signal reports:

“So what is the political fallout?

“There’s no doubt that with the decline in union membership here in Wisconsin, the political clout of the union bosses and their ability to automatically turn out members for Democrats has declined dramatically,” Brett Healy, president of the MacIver Institute, told The Daily Signal, adding:

When we look at the decline in union membership and compare it to the recent political fortunes of the Democratic Party, you can clearly see that when people are given the ability to choose whether or not they want to join a union we are seeing less people voting for Democrats.

After the Wisconsin Education Association Council’s loss of tens of thousands of paying members, it has become evident that the teachers’ union’s ability to influence the outcomes of elections and public policy decisions has waned in the past few years, Healy added.

“The Wisconsin Education Association [Council] was the single biggest political player in the capital, but after the passage of Act 10 and right-to-work, their membership, which is where they derive their political power, has declined,” he said. “A majority of teachers in Wisconsin have decided that their money is better spent in other ways rather than turning it over to union bosses.”

Unions are the financial kingpins of the Democrat Party.

Every left-wing cause is funded by forced union dues.

Right to Work not only fulfills the moral imperative of not forcing employees to pay tribute in order to work, but it drains the Democrat Party’s coffers.
