New YouGov research reveals stark division on the issue among the U.S. public.  32% support sending weapons to Ukraine, 37% oppose the idea, 30% aren’t sure.

There is a large partisan divide on the issue, with 53% of Republicans in favor of sending weapons compared to just 27% of Democrats and 25% of independents. There has been a marked shift since a July survey found Americans in all three political groups opposed giving military aid to Ukraine.

Republicans in Congress, such as Sen. John McCain and Sen. Ted Cruz, have been especially vocal in their support of arming Ukraine, though some Democrats and Obama allies have expressed interest in the idea, including the president’s nominee for Defense Secretary.
