From The Prince, Chapter 8 (Project Gutenberg):
Or, restated somewhat, if you must do something ugly to the people, do it quickly all at once, get it over with, so that you can start rebuilding your reputation over time by doing beneficial things gradually.Hence it is to be remarked that, in seizing a state, the usurper ought
to examine closely into all those injuries which it is necessary for him
to inflict, and to do them all at one stroke so as not to have to repeat
them daily; and thus by not unsettling men he will be able to reassure
them, and win them to himself by benefits. He who does otherwise, either
from timidity or evil advice, is always compelled to keep the knife
in his hand; neither can he rely on his subjects, nor can they attach
themselves to him, owing to their continued and repeated wrongs. For
injuries ought to be done all at one time, so that, being tasted less,
they offend less; benefits ought to be given little by little, so that
the flavour of them may last longer.
So if you are a Republican and you just lost a big election, now is the time to do damage and break things you want broken, because you have a few years before your next chance at power.
