What on earth for?
The more moderate candidates in the race, the better...they split up that share of the vote.
If Pataki were on the ticket, instead of the GOP losing New York by two million votes, they could narrow their losses and lose by a million and a half votes.
The chances of the Republican nominee carrying any electoral votes in the states north of Virginia in the Northeast are virtually nil, with the possible exception of New Hampshire. It won't make any difference if someone from one of those states is on the ballot.
