Long-time Senator Richard Lugar lost to Tea Party darling Richard Mourdock in Tuesday’s Indiana Republican primary contest. In a legislative body like the Senate where compromise and bipartisanship have long been necessary, this is another blow for getting things done.

In recent years, the upper chamber has lost – due to primary challenges, general election losses or resignations attributed to frustration with polarization – a number of moderates, including Olympia Snowe, Evan Bayh and John Warner. These Senators were often willing to buck their party leaders and cross the aisle on issues like climate change and energy security, forging the coalitions necessary to pass legislation.

Although not a central reason for why Lugar lost , Mourdock had criticized Lugar’s associations with groups like the Alliance to Save Energy and the Brookings Institution’s Energy Security Initiative. That’s because these groups had the nerve to endorse comprehensive energy legislation that would have dramatically improved the efficiency of our nation’s buildings and appliances while reducing costs. They also supported policies to reduce our dependence on foreign oil which increases our national security and protects our troops. All issues which should not be polarized by partisanship.

In his lengthy concession statement, Lugar focused on the costs of partisan politics and the need for elected officials to study the issues and sometimes take a different view than their party. He said,

“Too often bipartisanship is equated with centrism or deal cutting. Bipartisanship is not the opposite of principle. One can be very     conservative or very liberal and still have a bipartisan mindset. Such a mindset acknowledges that the other party is also patriotic and may have some good ideas. It acknowledges that national unity is important, and that aggressive partisanship deepens cynicism, sharpens political vendettas, and depletes the national reserve of good will that is critical to our survival in hard times.”

Protecting public health and our environmental safeguards not only confronts Congress on a daily basis, it is also moving front and center in the 2012 elections. At the same time, new science suggests that the consequences of inaction on climate change could be more severe than we had previously imagined and today renowned climate scientist James Hansen wrote a scathing editorial in the New York Times calling for serious action to be taken.

Lugar is correct to point out that the inability to work across party lines threatens our ability to address this and other challenges. That’s why the NRDC Action Fund is a nonpartisan organization working to rebuild the environmental majority regardless of party affiliation. We want to remind candidates that you can run on clean energy and protecting public health and the environment, because it’s what Americans really want from their leaders.

I can count on one hand the number of times I’ve been speechless. As a professional communicator, that’s probably a good thing. However, when the following headline: Heartland Institute compares belief in global warming to mass murder, reached my inbox this morning, I sat staring at my computer screen, with my mouth gaping, completely at a loss for words. Seconds later, after finally recovering from my initial shock, the words “now I’ve seen it all” came to mind.

While the Heartland Institute is known for its outlandish propaganda against climate change, this is a new low and might I say ill-advised attempt to win over the hearts and minds of Americans. A recent poll from the University of Michigan and Muhlenberg College Institute of Public Opinion shows that 62% of Americans believe climate change is real. This number is significantly higher than polling from just two years ago. The trend is linked to respondents acknowledging their own personal experiences as the main reason they believe the earth is warming.

Aside from the fact that solid scientific evidence and public opinion are not on their side, the Heartland Institute decided to plow ahead with comparing the majority of Americans (myself included) to Ted Kaczynski (the Unabomber), Charles Manson (a mass murderer) and Fidel Castro (a dictator) in their new ad campaign in Chicago. If, like us you don’t really identify with those notorious figures, you’re in luck. Future ads may feature Osama bin Laden. Seriously. I wish I was making this up.

There comes a time in all political discourse that someone must say “enough is enough” and this simply “goes too far.” The Heartland Institute should be ashamed of this type of extremist gamesmanship, which as the NRDC Action Fund previously blogged, “No one actually wins this kind of game. Instead, we end up with one big loser: the American people.”

What the American people want and need is a real dialog about how we can work together to invest in clean energy, while protecting our precious resources and the health of our kids. It’s time we all drew a line in the sand and told the likes of the Heartland Institute to stop these types of outlandish ads.
