“When will voters begin that long countermarch through the institutions in order to take back the country?”

This is not a problem that voters can fix.

Merely voting a bunch of Democrats out of office in 2010 or 2012 won’t solve the problem. See this post by Charles Murray. Murray looked at political self-identification, as recorded in the General Social Survey from 1972 to 2008, for whites aged 30-39 in six demographic segments: Traditional Upper, Intellectual Upper, Traditional Middle, Technical Middle, Working, Lower. For each year and segment, he subtracted the percentage of “conservative” and “extreme conservative” from the percentage of “liberal” and “extreme liberal”. In 1972 all segments were in the range +3 to -7. By 2008, all segments had moved right by 3 to 8 points, except Intellectual Upper, which moved 22 points left.

IOW, the segment of society which does most of the perceiving and analyzing and communicating (including teaching) has become overwhelmingly leftist. How can culture be reformed or rebuilt when the very basis of thought and action is distorted?

The Left has taken the intellectual “high ground”. It would take a generation of determined effort to re-establish any sort of balance. And the Left will resist fanatically any threat to its dominance.
