Charles and David Koch are each worth about $25bn, which makes them the fourth richest Americans. When you combine their fortunes, they are the third wealthiest people in the world. Radical libertarians who use their money to oppose government and virtually all regulation as interference with the free market, the Kochs are in a class of their own as players on the American political stage. Their web of influence in the US stretches from state capitals to the halls of congress in Washington DC.
The Koch brothers fueled the conservative Tea Party movement that vigorously opposes Barack Obama, the US president. They fund efforts to derail action on global warming, and support politicians who object to raising taxes on corporations or the wealthy to help fix America’s fiscal problems. According to New Yorker writer Jane Mayer, who wrote a groundbreaking exposé of the Kochs in 2010, they have built a top to bottom operation to shape public policy that has been "incredibly effective. They are so rich that their pockets are almost bottomless, and they can keep pouring money into this whole process".

The Kochs contributed to 62 of the 87 new members of the US House of Representatives in 2010. Members of the House Energy and Commerce Committee that the Kochs supported have taken the lead in opposing US Environmental Protection Agency efforts to reduce global warming emissions. Other members backed by the Kochs belong to the right-wing Tea Party bloc that took the US to the brink of default in July by refusing to consider a budget deal that would include tax increases.
In 2012, many believe that President Obama can raise a billion dollars for the presidential race, and break all fundraising records. But as Lee Fang of the Center for American Progress tells reporter Bob Abeshouse, in the end it may not matter "because the Koch brothers alone increased their wealth by $11bn in the last two years".
