1992 Election Results if Perot wasn't in and 60% of those votes broke for Bush

Seems reasonable. There's no way to know for certain how Perot voters would've voted if he hadn't been a candidate (obviously overall turnout would've been much lower).

Though I would point out that exit polls indicated the Perot vote would've split evenly between Clinton and Bush. Also, when Perot reentered the race in October, Clinton and Bush's percentages in the first Gallup poll immediately thereafter went down by the same amount as compared to the poll immediately preceding, and Clinton's lead was thus completely unaffected.

When Perot exited the race in July, Clinton went way up in the polls immediately thereafter, though obviously the fact that the Dem convention was going on at that time had something to do with it, as well.

That's true. It has been suggested that Perot took votes away from Clinton in the Northeast, but from Bush in the West. If so, he could have cost Bush electoral votes even while having no net effect on the popular vote. However, we would need exit polling or a more thorough precinct by precinct analysis to confirm this.
