Progressives push protest vote against Biden in Wisconsin Democratic primary over Gaza war. They are trying to get 20,000 people to choose this Tuesday the 'uninstructed' voting option, which was the margin of victory that the president obtained in that state four years ago over Trump.

Biden has already faced protest voting campaigns this year in several states for his management of the war between Israel and Hamas. A poll released last week showed that 55% of Americans disapproved of Israel's military actions in Gaza, up 12 points from November.
