Filibuster against Roberts is unlikely
The Gang of 14 Senators are meeting today to discuss John Roberts’ nomination to the US Supreme Court. Several of the Republican members of the informal group, including Sen. John McCain, have already stated that Judge Roberts deserves an up or down vote. Many of the Republicans among the gang of 14 have even praised Roberts. Sen. Joe Lieberman (D-Conn) said the president had recieved the message of the Gang of 14 and sent a "mainstream conservative" to the Senate for confirmation.
These positions are enough to indicate that while Roberts can’t expect an easy confirmation both parties are looking to move the nomination forward to the full Senate.
Roberts’ hearings and a vote are expected to begin shortly after Labor Day and last approximately one month.
