These are my thoughts:
She did something or some things in the past for which she is now being blackmailed.
I can’t imagine someone doing a 180 degree like she has done without the threat of public revelation of past history to things shady.
She was doing great until suddenly KA...WHAM!!!
You Arizonians need to replace her.
We wanted to replace her. The fact is her streak of hard core conservatism was all a lie. She’s a tax and spend liberal who refused to sign a budget that balanced until it included the possibility of a tax hike (she wanted the tax hike in the budget but settled for it as a ballot measure which she then “encouraged” to pass by threatening to slash the education budget if it didn’t). She’d irritated the hell out of almost everyone, it was looking like she wasn’t even going to get the nomination in her first election (lt governor is appointed in AZ). So she went “conservative” by rubber stamping everything that the GOP controlled senate passed, got the nomination, got lucky with the dem opponent and is now in.
So since she’s comfortably an elected governor now she’s reverted to form, which is a total RINO. There’s nothing sudden about now, the sudden ka wham was when she started rubber stamping what came out of the senate.
