Anyone who says they prefer Ralph Nader but then chooses McCain over Obama seems really confused about what Nader stands for. The fact is, my views match those of Nader more than any other candidate, but McCain is WAY down the list, far away from Nader's views.
If you go to
http://selectsmart.com/president/2008.html and select your views, it will match your views to those of the candidates and show you what percentage each agrees with you.

Here is the way the issues and the candidats match up with my views on the issues:
Ralph Nader   (81%)
Barack Obama   (76%)
Dennis Kucinich (withdrawn) (75%)
17 other candidates who ran in decreasing agreement until the
list reaches
John McCain   (20%)

So, Rig, your views agree with Obama a lot more than you think if you prefer Nader. If Nader's views and mine agree 81% and McCain only 20%, I really wonder why you would not vote for Obama. It must be something other than the issues.
