Tuesday's Michigan primary is shaping up to be a test of grassroots Democratic support for the president's pro-Israel policy in Gaza. Dima Hassan, a Palestinian born in Damascus, had to flee Syria in 2012 with her family after the start of the war.

In November, she will be able to vote for the first time as an American citizen. “Of course Biden is not going to have my vote. Not until she treats the Palestinians the same as the Israelis, until she commits to a permanent ceasefire,” she insists.
