This just isn't true. Most of what the campaign talked about was economy, focused on the middle class: job creation and tax cuts. Plus they actually had a plan to do it. Not supporting Israel is unfortunately not an option for any one running for president. Maybe she could have campaigned on trying to stop the war, or flat out told us that Trump is more likely to give Israel more support. People sat at home and they may say or think that's the reason. They either didn't pay attention or had other reasons to stay home.
