The problem with making a political alliance with evil men is that it is far too easy to forget that someone is evil when they are useful.

Sometimes, in order to defeat a greater evil, you must do it. But that never happens outside of actual physical conflicts.

The reason why it can work in a war is that wars have an end. Eventually, a peace will break out, one way or another.

But in democratic politics, that war lasts forever. Battles are won and lost,but barring governmental collapse, there is no permanent victory.

And during that entire time, those evil men are within your movement, warping it, changing it, hollowing it out until it is nothing but a desecrated mockery of what you thought it stood for.

But you can't get them out of the party, because you'd lose the next battle!

Sometimes, it is worth remembering that there are people of hood intentions on the other side of the political aisle, even if they aren't in power.

More importantly, we must remember that who we make our allies and comrades will effect us, for good or ill. If they are evil...
