The campaign today announced plans for the advertising as part of an outreach effort to counter "smears" against Ms. Palin. That outreach also includes sending surrogates such as former eBay CEO Meg Whitman to TV and radio shows.
The McCain ad is to compare Ms. Palin's executive experience as a governor who oversees 24,000 state employees, 14 statewide cabinet agencies and a $10 billion budget to Sen. Barack Obama's as a one-term senator from Illinois, the campaign said in a statement.
The ad itself wasn't immediately available.
The effort comes as the surprise choice of Ms. Palin, who is scheduled to speak tonight to the Republican National Convention here, continues to generate controversy.
