They're saving things for once they get rid of the losers guys, that's why they're doing the stupid raise your hand stuff now, and firing random shots to try and get something to happen. There's too many candidates anyway. It's like I said about the climate change debate idea, it just doesn't work in the format and with what the campaigns will want.
This isn't a big stage event yet, especially with so many candidates who will vanish, the targets are and will be Iowa, NH, SC and Super Tuesday states. And Democratic voters in those. And that's it because once those happen, it's too hard to come back against the leader.
Hillary's failure in the Blue Wall wasn't so bad because it happened, it's because it had already happened to her once with Bernie, and the response was to do absolutely nothing to change that while Trump basically lived in those states and Florida. And the polling WAS good for him there in comparison to nationally, especially versus prior elections and with likely voters over registered. That's why it was such a top to bottom failure. The metrics actually were right, but they wanted to turn Texas and Utah blue instead of actually ensuring the Blue Wall was protecting their flank by keeping the score up like the Obama campaigns did.
