Levi Johnston is a complete ass.
He is just trading off of knowing the Palins. If he maintained a consistent position there’d be no “news” and no reason to put him on TV. Presumably he gets a few bucks for being on TV, so why not change his mind and say something assinine so he can pay his rent?
If Sarah was a liberal, the MSM would have summarily dispensed Levi Johnston to the dustbin of history long ago.
