No, they have to move to the center.

As the article said Josh Shapiro and Andy Beshear would be considered centrist.

The US has already said it will start withdrawing troops from Europe and Hegseth considers China a bigger threat than Russia.

I already said that another option would be for the UN to be obligated to protect Ukraine if Russia attacks again. It would then be unnecessary for Ukraine to be in any alliance.

Trump should hit the reset button and start over. All tariffs should be removed except those protecting strategic industries. He should begin negotiating with countries he thinks has wronged the US before imposing tariffs on them.

Republicans are conservative. The progressive wing of the Democratic Party is too far to the left. Democrats must move toward the center in order to attract more voters. Note the centrist candidate in Romania just won.

To the contrary, I welcome criticisms my views in order to know whether they are correct or need adjusting. If you belong to a group in which everyone thinks the same, you will learn nothing. It's called groupthink. From https://www.investopedia.com/terms/g/groupthink.asp

Groupthink is a phenomenon that occurs when a group of individuals reaches a consensus without critical reasoning or evaluation of the consequences or alternatives. Groupthink is based on a common desire not to upset the balance of a group of people.

This desire creates a dynamic within a group whereby creativity and individuality tend to be stifled in order to avoid conflict.
