Election's over, Gas goes up

In the comments section on the KY3 Political Blog (http://ky3.blogspot.com/):
Decision 2006: The Polls Were Right,
one commenter made the following comment in regards to comments Senator McCaskill said:
"For instance, in the debate she said that oil companies were manipulating prices to try and help keep Republicans in office - and you never challenged her on the issue!"

Was she right?
How much was gas the 6 days preceding the election?
How much is gas now.
