Keith Koffler of THE WHITE HOUSE DOSSIER blog writes:

President Obama last night bought dinner for a dozen Republican
Senators as the two sides broke bread to try to begin reaching an
accommodation on the budget and other issues.

Senators are not used to skimping on meals, and the dinner must have
set the president – who paid out of his own pocket – back a pretty
penny. Or more like some Susan Anthony dollars… The outing at Washington’s posh Jefferson Hotel could easily have
cost a grand or two, especially if it was held at the Jefferson’s
exquisite Plume restaurant, which has a prix fixe menu costing $85, before you start including booze, which senators like to include… The meeting is part of Obama’s sudden new outreach to Republicans.
He invited the senators to the dinner, and he has also asked House
Budget Committee Chairman Rep. Paul Ryan (R-Wisc.) to have lunch with
him at the White House today. The committee’s ranking member, Democratic
Rep. Chris Van Hollen of Maryland, will also join them.m Emerging from the gathering, Sen. John McCain of Arizona gave
reporters the thumbs up, as did Sen. Tom Coburn of Oklahoma, who was
close to Obama when the two served together in the Senate.. Also dining Wednesday evening, according to the White House, were
Lindsey Graham of South Carolina, Kelly Ayotte of New Hampshire, Pat
Toomey of Pennsylvania, Saxby Chambliss of Georgia, Bob Corker of
Tennessee, Ron Johnson of Wisconsin, John Hoeven of North Dakota,
Richard Burr of North Carolina, Mike Johanns of Nebraska, and Dan Coats
of Indiana.

This occurred during the evening portion of Senator Rand Paul’s now famous filibuster. This can be seen as a sort of cultural break among politicos, activists, whatnot. Senators Graham and McCain easily are presented to represent the “establishment” and those present during the Rand Paul Filibuster, more importantly, those aiding in it, will be Tea Party favorites and “Conservatives”.

We get to see an active dividing line for the ideologues to point at.
