Why, oh why did I vote for Kyrsten Sinema in the first place?

9. I doubt that unless the Republicans essentially promised her the nomination

if she switched now would it make sense. Then she starts the race as the Republican incumbent.

Even then, as Senator Spector's experience shows, the Senate Republicans can not prevent a primary challenge. Where Spector was actually reasonably well liked and respected in PA and would very likely have won the general election that Joe Sestack lost, Sinema comes with high negatives. This is true for independents, Democrats and Republicans.

Given this year's Republican primaries, there is no way she does not get a far right, Republican challenger, like Kari Lake, who would beat her in the primary.

It seems what she is gambling on is the Senate Democrats endorsing her.
