You figure "30% of conservatives who are against Miers" is inadvertantly misleading. It's not as if the other %70 are pro-Miers. Most conservatives are undecided. And in my lifetime, thre has NEVER been this much conservative opposition to a Supreme Court nominee of a Republican President; not during Reagan's presidency, and not during the first Bush presidency. This bonehead Miers pick has split the Republican base, which is unprecedented in modern times. And because there are no good pro-Miers arguments, conservative opposition can only grow.
I did not say that 70% are pro-Miers. Do not put words in my mouth.
