For sending out a video linking Obama to pastor Wright, a McCain aide was suspended today. Jonathan Martin has the details:

Soren Dayton, who works in McCain's political department, sent out the YouTube link of "Is Obama Wright?" on twitter at 12:31 today with the tag, "Good video on Obama and Wright." It has since been taken down.

Twitter is an online device that allows users to send out short messages and links en masse through computers or PDAs.

McCain and his campaign have repeatedly said that they would stay away from personal attacks on Obama, but the temptation has increased as Wright's words have dominated the race in recent days.

Last week, they included an op-ed that hammered Wright and Obama in their morning clip package emailed to reporters. The same day, a campaign aide they regretted doing so.

Informed that Dayton was circulating the video, McCain spokeswoman Jill Hazelbaker said he had been suspended and "reprimanded by campaign leadership."

"We have been very clear on the type of campaign we intend to run and this staffer acted in violation of our policy," she said.

She declined to say for how long he was suspended.

As Martin says, there certainly is "temptation" to use Wright, but McCain has mostly ruled that out. I say "mostly" because McCain has vowed to run a clean campaign and this aide's actions certainly went beyond that. But, in certain circumstances, Wright is fair game, as long as one sticks to the facts, which this video didn't do.
