Those wacky PALINS are at it again – as they duke it out for supremacy of reality TV – if one of ‘em can actually sell a show!

 The Palin family is em­broiled in a war over reality shows, with hus­band Todd and daughter Bristol blasting “Mama Grizzly” Sarah for promoting her program while failing to fully support their bids, sources tell The ENQUIRER.

 “Sarah is getting flak from BOTH Todd and from Bristol,” said an insider.

 Todd’s proposed show about his snowmobile racing was shot down by both Discovery Communications and the A&E Network. And Bristol is strug­gling to reinvent her scrapped Bio channel reality show, this time under a Kardashian-style format featuring her boyfriend Gino Paoletti and her 17-year-old sister Willow.

 “To Sarah’s credit, she helped pitch Todd’s show,” noted the insider.

 “But he’s still furious. He thinks she didn’t work hard enough because it wasn’t centered around her.

 “And Bristol’s upset because Sarah wants to stay out of ne­gotiations for her show. Sarah isn’t thrilled with Willow being involved. But Bristol believes the show will be more marketable with Willow – that they can be the next Kardashian sisters.”

 Meanwhile, after Sarah an­nounced in October that she wasn’t going to run for presi­dent, on Dec. 19 she hinted that she might.

 But sources charge it’s just a ploy to raise her ex­posure as she seeks to bring back her own TLC reality show “Sarah Palin’s Alaska.”

“Sarah looks like she’s back in the very profitable business of will she? or won’t she? run for president,” observed another insider.

“She doesn’t have any serious plans to run, but she’ll keep the public guessing for as long as she can – or at least as long as she can make money off of it.
