You're trying to get people to look at Clinton and say "See, Bernie voted for war too, they're not so different!", it's obvious. The fact is that he voted against going to war, Clinton voted for going to war after seeing the exact same evidence. This difference creates a judgment call, Sanders had the judgment at the time to know (and call with incredible accuracy) that going to war would be bad for America. Clinton didn't. Any further votes to fund the troops fighting the war once we were already in it are irrelevant. When the decision to go to war was voted on, Sanders voted against it, Clinton voted for it.
They are not the same.
If you're trying to get Sanders supporters "on her side", I'd suggest highlighting the things they actually agree on and voted consistently on. Not the things they didn't.
