If Trump really has 90% among Republicans nationally, then Conway succeeded in getting him what he needed among the holdouts.

As I have been saying for Months, Trump needs to go for a massive win with indies with some kind of Perot style reform agenda. 90% of Republicans, 78% among Evangelicals, Massive turnout and support among Working Class Whites and a double digit lead among indies is a strong enough coalition to break the freiwal.
That impacts Colorado, it also impacts NC, PA, FL and the midwest, as well the two competitive New England states.
