Hillary Clinton’s presence will be felt in battleground states as the AFL-CIO is sending out literature to union members in Pennsylvania, Florida, Nevada, Ohio and Wisconsin.

“How you vote is a personal decision. Your union has done the research and recommends Hillary Clinton for President. Big corporation and right-wing interests continue to chip away at a worker’s right to organize,” the literature states.

The literature also does a side-by-side comparison of Hillary Clinton’s stance on worker’s rights to Donald Trump’s.

It asserts that Trump refuses to recognize a union election at his hotel, thinks wages are too high and believes that corporations should force workers to accept lower wages by threatening to move to lower-wage states. It also points out to union members that the GOP nominee supports “Right to Work” laws.

This direct mail piece is another example of the Clinton forces getting involved in the Keystone State. A Super PAC is already on the air and it appears her campaign will also be taking out TV ads soon.
