Matt Welch, editor of Reason, writes that John McCain's policies and rhetoric are a direct attack on the Individual:

The presumptive presidential nominee of the Republican Party has seduced the press and the public with frank confessions of his failings, from his hard-living flyboy days to his adulterous first marriage to the Keating Five scandal. But in both legislation and rhetoric, Mr. McCain has consistently sought to restrict the very freedoms he once exercised, in the common national enterprise of “serving a cause greater than self-interest.”

Such sentiment can sound stirring coming from a lone citizen freely choosing public service. But from a potential president, Mr. McCain’s exaltation of sacrifice over the private pursuit of happiness — “I did it out of patriotism, not for profit,” he snarled to Mitt Romney during the final Republican presidential debate — reflects a worryingly militaristic view of citizenship.
[...]
The senator’s ideas for “reform” — taxing cigarettes, banning ultimate fighting, giving the president a line-item veto — typically empower the executive branch at the expense of American citizens and their representatives. Even his efforts to prohibit torture and overhaul immigration proved hostile to individual rights. His ban on the cruel, inhuman and degrading treatment of detainees was packaged with provisions that jeopardized habeas corpus. And his immigration bill would have required American workers to prove their citizenship.

Welch brings up McCain anti-First Amendment leanings as well. And I have to admit that the "patriotism over profit" line that he hit Romney with during the campaign rubbed me the wrong way.
