If cash equals friendship, then John McCain and the oil industry are best friends.

The Arizona Republican has taken $1.4 million from oil industry employees in the 2007-2008 election cycle, more than any other politician, according to CRP.

That's over three times as much as Barack Obama, who ranks just below Hillary Clinton as the highest Democrat recipient.

With gas prices near record levels and the public clamoring for something to be done, now is a dangerous time for any politician to be taking money from the oil industry.
