Do nothing and just vote in the general. Trying to be clever often backfires. Some did this in 2008 thinking 0 would be easier to beat than HRC. That didn’t work out too well. I don’t think you’d feel too good if you helped Bernie Pete or whoever and they then went on to defeat the President in the general. Don’t inflate dim numbers ever.
With the bad economy and MCSTAIN as the nominee we were gonna lose in 2008, period.
