After releasing an ad -- or two or three -- per day, John McCain's camp announced Wednesday that, as part of suspending its presidential campaign in light of the financial crisis, it's also holding off on running or releasing any advertisements.

"In addition to suspending his campaign to return to Washington to work for a bipartisan solution to this problem, this campaign is suspending its advertising and fundraising," spokesman Brian Rogers said in a statement Wednesday evening. The duration of the delay was not specified.

This suspension leaves the GOP nominee's ad strategy -- outlined by McCain advertising guru Fred Davis at the GOP convention -- in limbo. Will the ads originally slated to run in the coming days be postponed? Will they run at all? Will this mean an influx of ads once an agreement is settled on the bailout?

Another question is how the suspension will influence McCain's outreach to voters compared to Barack Obama. The Democratic nominee has increased his ad spending by 50 percent and ramped up efforts in battleground states, while McCain has remained steady in both spending and market buys. Voters could see the suspension as commendable -- that McCain cares more about the financial well-being of Americans than the election. But it remains to be seen whether his absence from TV screens across the country will simply keep him "out of sight, out of mind" among voters more than anything else.
