(CNN) - His insight guided both of President Bush's successful White House bids, but aides to John McCain might just be hoping Karl Rove stops talking.
Days after the prominent Republican strategist said the latest McCain campaign ads had "gone too far" and failed the "100 percent truth test," Rove told the Associated Press Wednesday he thinks the choice of Sarah Palin was a political one and that the excitement she has generated will soon wear off.
"Nothing lasts for 60-some-odd days," he told the Associated Press. "Will she be the center of attention in the remaining 48 days? No, but she came on in a very powerful way and has given a sense of urgency to the McCain campaign that's pretty remarkable."

Rove also described the choice of Palin as a "political pick," and said she was not the most qualified Republican McCain could have chosen. But Rove also said Joe Biden, who has spent three decades in the Senate, was also a political pick - designed to make up for Barack Obama's relatively short resume.
"I think the American people have deep and persistent doubts about the readiness of this dynamic and charismatic first-term senator from Illinois," said Rove.
Rove's comments also come days after he wrote a column in the Wall Street Journal advising Barack Obama to stop attacking Palin directly, noting past attempts by Democratic presidential nominees to attack the No. 2 on the GOP ticket have largely fell flat.
“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 also told the AP Obama is an "arrogant dilettante," but continued to offer the Illinois senator advice on how to win the election: "The way that Obama can win is by explaining, expounding on who he is."
