Say some extreme bullshit to see if it gets enough support publically.
Walk back on it when there is too much backlash.
Do some non-apology or pretend you were misunderstood.
Pretend nothing happened and test if the next controversial statement is more successful.
That's page one of the populist's handbook. The main goal is only to find the statements with enough support so you can move the public discourse and the limits of what you can publically say further to extremes.
