Yes, I'm sure the AFLCIO and The Nation would never dream of publishing misleading political information.
Having just the vote itself is only a small piece of the issue. We don't know the details of the whole bill, we don't know what was debated, nor do we know why someone voted the way they did.
I randomly looked at one of these 'no' votes (adding 430 million to the V.A. outpatient care, some amendment to a larger bill in '06). The Republican "no" votes were:
Sam Brownback,
Tom Coburn,
Larry Craig,
Michael Crapo,
John Ensign,
Michael Enzi,
Judd Gregg,
James Inhofe,
John McCain,
Jeff Sessions,
John Sununu,
Craig Thomas,
David Vitter
That's pretty good company as far as I'm concerned.
