Nope. Actually Bernie supporters (myself included), understand our tax dollars should be appropriated to programs that actually benefit us. Medicare for all would save us around 9 trillions dollars.

And unless you make over 250,000 your taxes won't increase. Bernie is an FDR democrat and considered a center/moderate by pretty much every other countries standards. The US has swung so far right many are misinformed and don't understand this.
If you don't vote Bernie you are voting against your best economic interests pure and simple.
