Yes, she did.
Try and understand simple political math and logic.
When the conservative candidate is running 3rd, in a socialist hellhole state, with NO money, NO grassroots support up until now, and has been given 11 months to be the front-runner, you go with Plan B.
Plan B means supporting the moderate who is conservative on base-line issues such as taxes and spending, who has affirmed support for gun-owners, pro-life, and opposes illegal immigration, and who is not a bureaucrat or public official but who has business experience and millions of dollars at her disposal.
I'm sure Sarah agonized over this decision, and spent weeks doing so. But she looked at the bigger picture and decided that it was better to see Boxer and Campbell defeated rather than supporting someone who was given ample amount of time to state his case.
I understand political math and logic. I also know very well political movement. In case you have not noticed, the conservative wing of the party has not gotten any. The best that can be said is the pendulum has at times only slowed in its steady swing to the left.
Your plan B is not working, has not been working for decades. How many times do you advocate running head-on into the same wall?
Stand for your convictions, support them always and people will follow. Have you noticed with your approach how many are now registered as decline to state voters? What party do you think a majority of those voters came from, why did they leave and why do they stay home in such large numbers on election day?
In case it is not obvious, it is because they have given up on the compromisers, aka Plan B advocates in the GOP.
You can suggest my approach is wrong but don't tell me I don't understand this game.
