DeLay
David, at In Search of Utopia, defends his view of the significance of the divide in America by pointing to the Republican protection of Tom DeLay.
It isn't clear from David's post if he recognizes that the rule the Republicans modified is a Republican rule for Republican leadership, and a rule the Democrats have never had in place for disciplining their leadership. In addition, their modification of the rule is based on the real harm that illegitimate charges against Republicans can cause, the case most often cited being charges brought by the same man who accuses DeLay, against Kay Bailey Hutchison. A District Attorney with a mind toward attacking politicians to make a name for himself, rather than for justice, has led Republican leaders to modify their rule.
It is also worth noting that the rule change still requires the leadership to review and potentially remove the particular Republican leader should he be indicted.
Like many supposed liberals or progressives, the issue seems to be something other than securing Liberty, protecting Life, or expanding opportunity, it is once again espousing an illegitimate argument for the sake of power.
