Mike White, the chairman and owner of Rite-Hite, a major Milwaukee manufacturer of industrial equipment, told employees in an email this week that all employees "should understand the personal consequences to them of having our tax rates increase dramatically if President Obama is re-elected, forcing taxpayers to fund President Obama's future deficits and social programs (including Obamacare), which require bigger government."

The email stunned some employees. One employee said he felt threatened by the email. "It's a good company, but for this to come out, it's absurd," the employee said.

It's more than absurd, it's outrageous. It might be perfectly legal for employers to tell their employees how to vote, but that doesn't make it right—and I'm pretty sure most Americans feel the same way.

Don't forget, this isn't an isolated incident. In fact, earlier this year Mitt Romney encouraged business owners to tell their employees how they should vote. That's exactly what happened in this case.
