The maneuvering in the Senate is intensifying around the Iraq escalation question, with two new GOP Senators saying that they may introduce their own resolutions on President Bush's plan, today's Los Angeles Times reports.

John McCain, the leading advocate of escalation, and GOP Senator John Cornyn both are saying they may introduce such resolutions, the obvious goal being to give Republicans something to support so they don't break ranks fully and back the tougher resolutions fully opposing the surge that have already been introduced.

Though few details are available on the two planned resolutions, Cornyn's resolution would effectively endorse the "surge," while McCain wants to create some sort of way of measuring the effectiveness of the "surge" -- a move that could blunt the criticism of those who say McCain is sinking more and more American lives into Iraq with no regard for whether this is at all likely to be effective.

The maneuvering around Iraq is probably the single most important unfolding drama in the Senate right now, with extensive implications for the 2008 Presidential and midterm elections.
