I've just dared to update the title of your OP, so that we clearly see that it's round 2 (and not still 1): otherwise, nobody will vote...
The global turnout will probably be low again this week, so let's not depress it even more
.
And my vote:
A:
CNN (they are really bad, you know ?) and
MagellanB:
Franklin & Marshall (though Fox isn't far behind on my list) and
Harris Interactive (for the latter, my pick is more based on utter French polls than on US one
)
C:
LA Times and
NewsweekD:
NBC and
Democracy Corps
