Senate Democrats are preparing to join Republicans in passing a resolution in support of Israel. The bill will rebuke Obama’s call to make the 1967 lines the guideline for negotiations. Clearly they are worried about the political implications of Obama’s speech.

Senate Democrats are expected to support a resolution intended as a rebuff to President Obama’s call for basing Middle East peace talks on the 1967 Israeli-Palestinian borders.

It would be a rare rebuke of the president by the upper chamber and a sign that Democrats are worried about the impact of last week’s speech on the U.S.-Israel relationship and pro-Israel constituents.

Democrats in both chambers are scrambling to fix the damage caused when Obama called for the 1967 borders and land swaps as a basis for peace.

If this happens, it will be a big blow to Obama.
