The NRA didn't just throw down the gauntlet to our government in Houston. It also articulated a vision of America and its ideals that is the antithesis of what our Founders intended, and which would mean the absolution of our Constitution.

We sometimes forget that getting laws passed and getting court rulings declared is, comparatively, the easy part. The hate is still out there, however, and the haters are getting more desperate. Our worst enemies right now are complacency and the seductive message that we've "arrived."

I might suggest that we first take a deep breath and make an effort to put the events of the past week in some perspective, but I know it wouldn't do any good. There is blood in the water and in deeply partisan Washington, the struggle for advantage and power always trumps reality.

Richard C. Levin

President of Yale University

We leave together. You leave Yale College after four years; I leave the Yale Presidency after twenty. I find myself thinking about a Grateful Dead song written in 1970, the year I came to Yale as a graduate student. You know the words: "Lately it occurs to me, what a long, strange trip it's been." It's been a long trip, but, for us, more wonderful than strange.

What a week for Republicans! It started with Obama fighting off simultaneous scandals and 24 coming back this Fall. But as Spitzer and Reagan discuss, by Friday the Scandals Scorecard revealed more smoke than fire. Who'll tell FOX?

For five years we've watched the Justice Department ignore overwhelming evidence of bank crime. That's what makes this letter from Sen. Elizabeth Warren so important.

International President, United Steelworkers

Permitting Tea Party, left-wing, libertarian, middle-of-the-road -- whatever -- groups to define themselves as untaxed social welfare organizations that may accept unlimited, untaxed, secret corporate gifts and sponsor political ads is a sarcoma on democracy.

Don't want a children's toy containing lead paint manufactured with child labor in your state? Congressman King and the House Agriculture Committee say "tough." Want the workers in your state to have a better chance? Your state won't have the right to choose. The Feds are encroaching.

The student loan program calls attention to the double standards of debt relief. Corporations are able to declare bankruptcy under Chapter 11 and write off old loan -- but college debt follows former students literally to the grave even if they go bankrupt.

Eli Lehrer

President, R Street

For all of its populist appeal, the corporate income tax is arbitrary and exempting some organizations from paying it is equally arbitrary. Abolishing the corporate tax altogether would supercharge the economy and wouldn't serve any particular set of political interests.

Barack Obama visited Morehouse College on Sunday to give a refrain on the responsibility of Morehouse Men and black America to find dignity and progress in self-reliance, a refrain that has simultaneously proven exciting and excruciating for African Americans over the last four years.

James Peron

President, Moorfield Storey Institute

As bad as drugs can be, Drug Warriors are worse. They raise the stakes of the drug fight, incentivize the drug gangs and push them to greater heights of violence. When a solution becomes worse than the problem it is time to abolish the solution.

International Affairs Master's candidate, New York University

Taliban resurgence could immediately undo any improvements made under U.S. occupation, as could economic collapse, civil war and regional instability.

Miles Rapoport

President, Demos

Almost 16 million Americans have registered or re-registered every year under National Voter Registration Act provisions. Many people today don't remember a time when they couldn't register at their local DMV. Yet, there is work to be done.

I have a huge issue with what happened that day. And what happens to me every single time I go to an airport. This was supposedly a random search. But it wasn't a random search at all. It was a "you're a Muslim" search.

William S. Becker

Executive Director, Presidential Climate Action Project

In picking Gina McCarthy to lead the EPA, Obama sent the Senate a nominee who should satisfy, if not delight, Republicans as well as Democrats. But these days, the Senate rarely stumbles in the right direction. Senate Republicans are playing games with Obama's selection.

Earl Ofari Hutchinson

Author and political analyst

there's the almost ritual expectation by the public that second term presidents will be dogged by some scandal. This was the case with Eisenhower, Nixon, of course, Reagan, Clinton and George W. Bush. This shouldn't surprise.
