Yeah, there's that I guess. But isn't the message that the GOP "is against solving the border crisis" worth something? Just like saying that the GOP wants a national abortion ban?

Eh, not that much. You want to nail the GOP on the national abortion ban because the electorate generally sides with the Democrats on that issue. Obviously people differ greatly - but generally speaking, more voters will say the Democrats best represent their position on abortion than Republicans. So you want them to be thinking about abortion when they go into the voting booth. With the border, it's the opposite.

You can claim that the GOP "is against solving the border crisis," but it's not likely that too many voters will believe that. Oh, sure - they voted this bill down. But the GOP also gets to campaign, and they'll certainly take the position that the bill wasn't strong enough to do the job. That's probably wrong (and disregards the fact that irrespective of whether this bill is "strong enough," it's the strongest bill that might ever get out of a Congress where the Democrats have more than 40 Senators). But that won't matter. If you're arguing, you're losing.

Run on abortion and low unemployment and "democracy" and how terrible Trump is. Use the border bill as a defense against attacks on that issue, but don't center it in your campaign.
