[JURIST] Conservative activist groups are stepping up their opposition to US Supreme Court nominee Harriet Miers [JURIST news archive], launching two new websites Monday and also planning radio and television advertising aimed at forcing the withdrawal of the nomination. The nomination has seemingly lost all support from base conservative groups. According to Brian Burch, a spokesperson for Fidelis [advocacy website], a Catholic pro-life organization, such groups "really do want to support the administration, but we just feel like we've reached a situation with this nomination that is beyond repair." One website launched yesterday, WithdrawMiers.org [advocacy website], features articles critical of Miers, a box where readers can submit anonymous tips on her nomination and a petition calling for her to step down. Another website, BetterJustice.org [advocacy website], features a television ad proclaiming that "Even the best leaders make mistakes," referring to Bush and his Miers nomination. Tuesday's Washington Post has more.
