What, in your opinion, is it about a second rally after the one he already has scheduled in both states that would assure Trump winning two safe blue states?
I said two or more for any of the states he's already scheduled a rally for. Not a second one.
Trump is scheduling the rally in Aurora, Coachella and MSG based on his internal data. That data will continue to change, and where he speaks will reflect that. That's why I've always said watch where he speaks, as that tells you where this race is REALLY at. Because his internal data is dictating his schedule.
The states he is speaking at are either the current tossup states, or the states where he is behind but gaining. So according to his data, CA, CO and NY all fall into one of those buckets.
If he adds a rally next weekend to Boulder, then the weekend after that he adds another in Aurora, that tells me he thinks CO is in play, and in that case I would say he will win CO.
Same thing for him adding two more rallies in NY or CA.
If he doesn't schedule another rally in either CA or NY, that tells me that the first rally didn't move the needle as he wanted, so he's not going to go back. Or it could be that one of the other states has tightened so he thinks it's best to go to that state instead.
As I have always said: The states that Trump speaks at in the final 7 days before the election are the true tossup states.
