ABC News' Michael Falcone reports:

How seriously is the Romney campaign taking the possibility of a post-Election Day recount ?

Romney campaign officials have instructed members of their staff from the political and advance teams as well as other departments to "pack a bag" and bring it with them to tonight's election night event at the Boston Convention and Exhibition Center.

Each notified staffer would be part of a "go-team" to be dispatched to one of several states where a close result might lead to a recount. (Inside the campaign, Ohio is the state that has loomed largest in discussions.)

Campaign planes are said to be on stand-by to ferry staff to their as yet unknown destination if needed.

In the state capitols of many of the battleground states, the campaign has also kept a small team of advance staffers who would also be ready to spring into action.

"We're expecting a clear and decisive victory tonight," a Romney campaign official told ABC News, "but we're obviously ready for any scenario."

The campaign already has both volunteer and staff lawyers camped out in all of the swing states .

Team Romney has also set up a "war room" at the TD Garden in Boston where a team of the campaign's top legal officials, including Benjamin Ginsberg who played a lead role for George W. Bush's campaign during the 2000 Florida recount, are monitoring potential problems at polling locations.
