Yes, it's really pretty straightforward.
Lincoln has been "accused" of preserving the Union and protecting the territorial of the United States. And, nowadays, our recent presidents have been criticized for failure to protect our borders. I want a president who protects the USA. I think that is why Lincoln is so popular now and why our recent presidents are so unpopular.
Some people don't seem to understand that a declaration of "secession" includes the improper attempt to unilaterally cancel the citizenship of U.S. citizens and the attempt to deprive those U.S. citizens of their rights under the United States Constitution. I want a president who stands up for such citizens and who won't tolerate any efforts to separate U.S. citizens from their national government, their national identity and their fellow Americans. Since Lincoln, we know that there is no excuse or justification for that kind of behavior.
I wish that more of our presidents today could learn what should be a simple lesson from Lincoln: the USA is worth protecting at any cost.
Abe Lincoln - He would have built a wall to protect our borders!
“Some people don't seem to understand that a declaration of “secession” includes the improper attempt to unilaterally cancel the citizenship of U.S. citizens and the attempt to deprive those U.S. citizens of their rights under the United States Constitution”.
Secession did not affect anyone’s rights. If you read the minutes of the
Montgomery meetings, it shows that your assertion is completely wrong.
