Collins, and Murkowski didn’t vote to convict last time and the calculation for them is the same now.
If McConnell votes to convict he might as well announce his retirement.

They aren’t going anywhere soon
Well, McConnell may well retire at the end of his term, anyway. His more immediate problem might be not being able to ever set foot in KY (and several other states) again.
He already announced he is not running. It is that time in his life where he lets the “old lady” take over the family business.
