^Aside from the repressiveness of the policies themselves, there are three highly significant and enduring harms from Obama's behavior. First, it creates the impression that Republicans were right all along in the Bush-era War on Terror debates and Democratic critics were wrong...^

^Second, Obama has single-handedly eliminated virtually all mainstream debate over these War on Terror policies. At least during the Bush years, we had one party which steadfastly supported them but one party which claimed (albeit not very persuasively) to vehemently oppose them. At least there was a pretense of vigorous debate over their legality, morality, efficacy, and compatibility with our national values.^

^Those debates are no more...^

^Third, Obama's embrace of these policies has completely rehabilitated the reputations and standing of the Bush officials responsible for them.^
Notice that the "harm" he discusses is not to the nation, or our national security, but to the Left. Of course, to the Left, that's all that's important.
