Dems response to Harriet Miers?

I was reading page 2 in the KC Star this morning (my favorite as it provides 3-5 quick hits which are well written and concise). I'll just note it word for word:

Apropos to the debate over Miers' religion, Article 6 of the Constitution unequivocally says that "no religious test shall ever be required as qualification to any office or pubic trust under the United States".

I mention this because it seems to me that if a Democrat wants an excuse to vote against Harriet Miers without seeming partisan, a remark that President Bush used a de facto religious test (thereby violating/opposing the Constitution), would seem to work here.
