Karl Rove says former Alaska governor and VP presidential candidate Sarah Palin is more likely to run for President than not. A formal announcment may come Sept. 3.

In a Fox News interview Sunday (see the video below), Rove said a video released on Friday by Palin's political action committee looked very pre-presidential. Rove is a former advisor to President George W. Bush and a key Republican activist and fundraiser. Palin is a Republican as well, with close ties to Rove.

She joined Sen. John McCain, the Republican presidential candidate, in a run against Barack Obama the the campaign was marred by disorganization and lack of a clear message that resonated with the public. In the couple of years since, Palin has become a recognized conservative spokesperson and celebrity.

Palin has been coy on whether or not she's running for President, but Rove says it appears she's likely in.

The schedule she's got next week in Iowa, it looks like that of a candidate, not celebrity, he said on Fox News Sunday.

Palin has a major speech scheduled for a Tea Party event in Iowa on Sept. 3. Rove suggested that speech is prime for announcing a presidential bid. But Rove also says if Palin doesn't get in by then, he and other Republicans may have a hard time supporting her.

Her difficulty is, if she doesn't get in shortly after next week, then I think people are going to basically say she's not in, she won't be in, if she gets in, I'm not going to be for her, Rove said. You can only tease so many times in the political process, and I think she is getting to the end of that.
