How about a little politics?
Relating it to the environment, here is an interview with Biden (Obama's VP) on energy and environment. Personally I really like his positions.
With Palin (McCain's VP), she's so new to politics that not much is known about her environmental positions. She seems to favor drilling in ANWR, her husband works for oil company BP, but she also successfully taxed the profits of oil companies in Alaska. Basically she's very pro-drilling, but not necessarily in the pockets of Big Oil.
Polls have shown that most people know jack squat about Palin. She's been governor of Alaska for about 20 months. Prior to that she was mayor of a city with a population of around 6,000. She also won some beauty pageant at one point. Coincidentally, the population of Alaska is only slightly higher than the population of the district for which Obama was state senator for 8 years. So inexperience is out the window.
My personal opinion is that Biden was a very good pick by Obama. He balances out the criticism of inexperience, particularly on foreign policy, he's good on the environment, has a great personal story, etc.
I also think Palin was an incredibly dumb choice by McCain. One of his best criticisms of Obama was the difference in experience. That's completely shot now. McCain is 72 and not in superb health, so Palin could very easily become the president of the US if they're elected. And her experience is limited to governing the 3rd-least populated state in the country for 20 months. Wow. She doesn't bring the economic strength to balance out McCain's weakness on that issue like Romney would have. Basically as far as I can see, the only thing she brings to the ticket is her ovaries.
It seems like the choice is purely an attempt to woo disgruntled former Hillary voters, but just a couple days ago Hillary did a great job convincing them to vote for Obama. I'm not sure McCain could have made a worse pick. The only upside is that it's drawn all the attention away from Obama's speech at the convention last night (which coincidentally, was a really great speech).
What does everyone else think?
