The problems come with "Well, I won't vote for you then! I might just stay home and not vote at all!"
When you get there. Why should they cater to you? When they might cater slightly not to you, can get a person who will vote 100% of the time. This is my argument.
If you read my post. My argument is for the politically disatisfied people in the US to organize in the grassroots. While keeping the federal as "least bad". Because changing the US from the top-down is impossible. However, changing it from the bottom up with a 7-2 conservative supreme court will also be impossible.
Well, if you go about it the right way. Looking at the long game. It could work.
However, that wouldn't be "go for the POTUS!" It would be "go for the states". And then jam the economic rightwing people together into one party getting the overton window back to where it was pre-southern strategy.
This can't happen from the top down. It has to happen from the bottom up. Americans will however, probably be lazy and just whine about the federal level stupid.
