I didn't see this mentioned anywhere, so I thought I'd float it:
According to an article in last December's Newsweek, one of Tom Delay's "questionable contributions" came from the law firm that Miers headed.
"Among the contributions at issue: a $1,000 check in 2001 from superlobbyist Vin Weber, whose clients included Microsoft and the Pharmaceutical Research and Manufacturers; and $2,500 that same year from Locke Liddell & Sapp, the Texas law firm formerly headed by Harriet Miers (who was recently named White House counsel), which was then representing Burlington Northern Santa Fe."
That may have the potential to cause a real media stench.
