Could you see big GOP supporters, donors an the RNC abandon this ship in 2016?

What I mean is, if there is simply too much negatively surrounding the GOP and its candidates, could bigtime donors and the special interests simply write 2016 off very early and plan to try again in 2020?

Usually by mid-September and October (the latest), big corporations and even the DNC/RNC will cut candidates off cold once internal polling shows their candidate is either toast, or that supporting them will cause more angst for the company itself?

If this GOP train wreck continues, could you actually see this happening where Trump or Cruz are completely abandoned and left to die on their own?

Usually, and especially in a presidential race, there is a coming home effect where to some extent, there is an "all in" mechanism that kicks in at the end, where the candidate is unified by his/her party, but I'm not so sure that happens this time.

While I wasn't alive then, the '68 Democratic Primary could have been an example.  The party was badly fractured, the DNC was a disaster and it looked like Nixon would win going away.  But, the party slowly started to unite around Humphrey and as Wallace's support declined in the final six weeks, Humphrey had all the key momentum at the end, which almost yielded an improbable victory.

Thoughts?

It's already pretty clear that if _trump is the nominee there will be many donors and volunteers that will simply sit this year out. _trump will get their literal votes, but that's not what he needs from them.
