This is a good example of why I am very skeptical of - and I don't trust - Rubio.
You guys should be very careful with this, infighting at this stage of the game is still dangerous, but you can't let the neo-cons walk over you.
My suggestion, troll Marco Rubio.
Don't attack or criticise him, mock him into submission and ensure that Trump knows he has the support and leeway to afford risking his relationship with the neo-cons based to protect good virtuous people like this man.
Share this topic where you can, but frame it in a lens that doesn't strengthen the left.
A good way to do it, would be to suggest Marco Rubio probably argued with him over Israel. Sine on the left hate Israel, and some don't, but forcing them to defend either the USAID destroying isolationist conservative, or the Israel loyalist neocon will scatter their attempts to use this information as propaganda and leave their forces in disarray.
Best part, it's probably true.
Marco Rubio is pro-Israel after all.
