Scott Walker is doing a weekend tour of New Hampshire for his not yet ready for prime time presidential campaign even though he's not yet an official candidate.

The good news is that he is no longer comparing Wisconsin protesters to ISIS terrorists.

The bad news is that Walker is still comparing ISIS to a computer virus:

"I think our clearest threat right now is radical Islamic terrorism. I see it right now embodied in Syria and Libya but growing elsewhere around the world and I just believe fundamentally when you listen to leaders of organizations like ISIS and other like them, it is clear what their intent is. It's not to stay in the Middle East. It is eventually to come back to American soil and to cause harm against Americas because that's their identified threat there. And so, my belief is that, just like a virus in a computer, that we need to go and to whatever length is required to make sure we eradicate radical Islamic terrorism wherever it's at before it washes up. I don't believe that you automatically go with ground troops, although, unlike this president, I will not signal to our enemies how far we will go."

I'm sure that Walker still considers himself qualified to deal with ISIS terrorists - as well as North Korean hackers and net neutrality issues - because he had a secret router and a secret email system.

Now, I'm no computer expert but it seems to me that the best way to deal with a computer virus is not to get one in the first place. You do that by downloading antivirus software and by not partaking in activities that would increase the likelihood of getting a virus.

Translating that to Walker's example, it would mean building up our nation's infrastructure to make it stronger and not invading every oil-rich nation just because your corporate sponsors want you to.

But Walker would never say such a sensible thing. He is putting all his money - er, all the Koch's money - on the fringe element of the Republican Party, which requires him to keep blowing the dog whistles and feeding them their red meat of fear and bigotry.
