Could NY-Gov have been competitive if the GOP spent money on it?

[tpfkaw]

Cuomo ended up winning by a much narrower than expected margin of 54-41, at the same time as Republicans did very well in the congressional races and took back the State Senate.  Since all the polls and conventional wisdom said that Cuomo was going to win in a huge landslide with a margin of nearly 2-1, Rob Astorino's campaign had pretty much zero resources, while Chris Christie announced that the RGA wouldn't spend anything on the race and refused to campaign with Astorino.

If Astorino's campaign, the RGA, and/or a Republican super-pac had been able to spend $10mil or so on an actual campaign with well-produced TV ads in heavy rotation and a ground game, and had pulled off one of those classic NY dirty tricks by financing a "Progressive Party" line for Zephyr Teachout, would Astorino have had a decent shot? I'm leaning towards yes.
