I would interpret that as "strength in numbers." President Trump always talks about his turnout and size of the crowd; he always mocks the LAAP-dog media for not turning the cameras around to show the true crowd size at his rallies.
In politics, "strength" means votes and the size of voting blocs. By amassing a large crowd of like-minded people, Trump is sending a message of "strength" by the size of the crowd that assembled to hear him.
It's what Dr. Martin Luther King, Jr., did with his "I have a dream" speech by showing the size of the crowd that he can command.
I'm not intending to compare Trump to King other than to show that it's a compelling show of strength to draw very large crowds compared to others.

You would. Did those who went to the Capitol ? Trump has to a degree cozied up to those actions by those who did take his words a bit more seriously as time has gone by. His pardon talk is but just one way.
