A Catholic-evangelical split?

From a Tim Chapman column:

Much has been made of Miers evangelical background and conversion to Christianity. Miers membership in a “fundamentalist” (indicating orthodoxy) evangelical church has been a White House selling point to influential evangelical groups whose support for the nomination is seen as crucial if Miers’ bid for a seat on the Court is to weather the initial storm...

...But this line of argument is troubling to many conservative Catholics. Miers was a Catholic before her conversion to evangelical Christianity. There is a concern that the consistent emphasis on “born again” Christianity may alienate conservative Catholics who are an essential part of the President’s pro-life conservative base.

Troubling? For me, at least, it is not so. I would be interested in our readers' and editors' take though.
