Should employers be allowed to discriminate on the basis of political views/affiliation? [View all]

[PlanetaryOrbit]

I read an Internet comment by a boss who decided to lay off employees based off of whether they had Obama bumper stickers or not (he was laying off employees that did support Obama - again, this was an Internet comment, so take it with several grains of salt), and it got me wondering:


Should employers be allowed to hire, fire, promote, not promote, or otherwise discriminate on the basis of political views or political affiliation?



I understand there may be valid need to do so - why should a liberal political party be required to hire a conservative who doesn't share their views? - but for the most part, should such discrimination be banned?
