The Ballot Box is the narrow choke point through which every political cause must pass. The Left controls the ballot box pretty much everywhere which is why we saw the blue wave. The Right was able to get Trump elected in 2024 because they managed to control the swing states.
Passing the SAVE act is probably the most important thing Republicans can do right now.
It's past the House, but Trump should focus heavily on getting it through the Senate while before the next congress is sworn in, or do it by executive order.
