Colorado is among the firewall states, if trump can break it game over folks.
If trump wants to win here he must increase his lead with INDs to double digits in this poll he leads by +6 (with 15% undecided), In Quinnipiac poll+9 and in Emerson poll +15 (estimated).
He also needs to solidify his position with republicans ( 17 % of white evangelical undecided).
There's no such thing as game over when he's tied in Florida, especially with what we know about trying to poll Spanish speakers accurately. If Clinton takes Florida, that's the election right there,
regardless of what happens in CO or NV or ME or NC.
If trump prevailed in CO, no way he can lose FL,NC and ME 2.I am not sure about Nevada which he does not need to win at that point.
