Trump can help regain his high 2016 Evangelical Christian vote whilst increasing his very low 2016 Jewish vote by green-lighting Israel's immediate application of sovereignty in Judea and Samaria -considerably boosting his prospects for re-election.
Green light on Judea and Samaria is key to Trump's re-election
President Trump's chances of winning another term in November could well turn on his publicly endorsing Israel to immediately implement his Peace Plan restoring Jewish sovereignty in 30% of Judea and Samaria (aka West Bank) after an absence of 3000 years.
Judea and Samaria--the ancient and biblical heartland of the Jewish People—was expressly designated by the League of Nations Mandate for Palestine in 1922 as part of the area within which the Jewish National Home could be reconstituted. That right still survives in 2020 under article 80 of the United Nations Charter.
