For people opposed to a theorcatic state I would worry less about the person elected and more about the fact that he was elected. I'm sure this information was availible prior to the vote.
Remember, in our system you can advocate for its overthrow as long as you do it via the ballot box. Nothing can stop a group from changing even the constitution itself if they get to the proper margins.
Now, remember this is ARKANSAS, one state, in the deep south. Hell some people up in the mountains are STILL FIGHTING the Civil War.
Hey, I spent 6 years in the Arkie Ozarks. It's a little more complicated there than you paint it. Are there folks still fighting the Civil War? Of course. But then there are huge parts of the State that are more Midwestern or Southwestern than Deep South, and there are also areas where the education, economic and overall sophistication level are higher than a lot of places I've lived in the Northeast. Being from Arkansas is no excuse.
And I do have a problem with a Christian Reconstructionist being in a position to influence law, even if most of his colleagues will reject his proposals. Theocracy is anathema to everything the US stands for. It should never be written into law. You have a point about the people who voted this guy in, but then again look at all the people who voted for O'Donnell in the DE primaries without knowing information that was out there, and regretted it later.
