(CNN) - Karl Rove is again offering unsolicited advice to Barack Obama, this time advising the Democratic presidential nominee to avoid attacking Sarah Palin directly if he hopes to win the White House in November.
“It's a match-up he'll lose," Rove writes Thursday in his regular Wall Street Journal column. "If Mr. Obama wants to win, he needs to remember he's running against John McCain for president, not Mrs. Palin for vice president."
Rove notes past attempts by Democratic presidential nominees to attack the No. 2 on the GOP ticket have largely fell flat, and says the issues Obama is hitting Palin on are ones the Illinois senator is weak on himself.
"If Mr. Obama keeps attacking Mrs. Palin, he could suffer the fate of his Democratic predecessors. These assaults highlight his own tissue-thin résumé, waste precious time better spent reassuring voters he is up for the job, and diminish him - not her," Rove writes.
Specifically, Rove says it is not in Obama's interest to attack the Alaska governor on her lack of experience or the earmarks she has requested - two issues, Rove says, on which voters may also question Obama's record.
Since she was named to the GOP ticket two weeks ago, Obama has rarely called out Palin directly, often attacking both her and McCain together as representing a continuation of President Bush's policies. But in an interview on CNN last week, Obama suggested his executive experience surpassed Palin's.
“My understanding is that Gov. Palin’s town, Wasilla, has I think 50 employees," he said. "We've got 2500 in this campaign. I think their budget is maybe 12 million dollars a year – we have a budget of about three times that just for the month."
He also on Sunday called out her claim she is an anti-earmark reformer, saying "I know the governor of Alaska has been saying she's change, and that's great…[but] when you've been taking all these earmarks when it's convenient, and then suddenly you're the champion anti-earmark person, that's not change….you can't just make stuff up."
