If he seems slippery on the topic. From The Note today:

After showing a clip of Romney telling “This Week,” “Our belief is just like it says in the Bible. The Messiah will come to Jerusalem,” ABC News’ George Stephanopoulos said Sunday on “Good Morning America”: “We checked in with a Mormon spokesman. They say it’s not actually true. They believe the New Jerusalem is in Missouri and that’s where Jesus is going to come.”

UPDATE:

An e-mail:

Subject: Jerusalem
I don’t know who the Mormon “Spokesman” Stephanopoulos spoke with, but the spokes-dude ought to attend Sunday School at his local Mormon ward.
A whole section in Mormon scripture called the Doctrine and Covenants (section 45) affirms and reiterates the Bible position that at his coming Christ will stand on the Mt of Olives, which is in Jerusalem (cross ref to Zech. 14: 4).

Another e-mail:

Rich,
Leave the religion crap out of it.
I am Mormon and we believe absolutely that Christ will come to Jerusalem to the mount of Olives and the Old Jerusalem. We also believe that Christ will come to the New Jerusalem in America.
I could quote you biblical scriptures about why we believe this way but why should I.
Romney was right on concerning this point of doctrine. He chose not to emphasize the Mormon belief about the New Jerusalem but focused on the common beliefs of other Christians.
I will repeat again. We believe that Christ will come to the Mount of Olives in the old Jerusalem. Period
This is getting ridiculous. Talk about relevant issues.
