Do you even have the slightest idea who the largest voting block is? People don’t need to vote for a Republican for Biden to lose. They just have to not vote.
It’s amazing you even posted that as a response.
Sure, I would advocate for Republicans not voting for Republican legislators, if the Republican base wanted a ceasefire. But they don’t. The Republican party is afraid of their base. The Democratic party has contempt for theirs.
Also, Biden already started shipping those weapons, regardless of that vote. Holding up the weapons temporarily was an attempt to look like he was doing something, same as the floating pier was. Did you even read the link? It hasn’t passed the Senate yet.
