The progressives (bernie, AOC, etc.) had very very disappointing responses to Ukraine that showed they are not ready to rule. I was particularly devastated by AOC's response.
The Carter presidency is in the running for the most peaceful modern presidency. He did start arming the rebels in Afghanistan, and ordered what I guess amounts to a brief invasion of Iran, but overall, pretty peaceful. It's either him or Trump.
Truman, Johnson, Clinton, Obama, etc.
The only difference between now and the 70s is that the politicians have more control over the left.
