Today, the WSJ has an article up on Miers participation in Jones v. Bush, which was suit filed to prevent Texas electors from voting Bush-Cheney. The 12th Amendment, of course provides that a state's delegation can't vote for presidential and vice presidential candidates who are both from electors' home state. The is was whether Cheney was a citizen of Texas or Wyoming. According to the article, Miers argued for a liberal interpretation of the so-called habitation clause.
It is an interesting article, but we can't draw too much out of it. Miers was acting as an advocate and was making the best arguments she could on her client's behalf.
