I might agree with that in general -- but you sound as though they are entirely on the Obama side. Both sides of the political spectrum have ardent followers that tie themselves to parties without question.
Well followers on either side that tie their vote strictly to the letter beside the name of the candidate are certainly practicing lemmingesque behavior. I'd also suggest the rock star following Obama has garnered holds large numbers of people that would follow him over the cliff. The guy could change his opinions to the ones TennNC suggested and many of his current backers would think- "Wow, those are great ideas, never thought of things that way!".
