In theory term limits seem like a good idea. But never underestimate the depths of evil creativity that flourishes among the political class.
If term limits became law, I suspect their reaction would be to form groups of like-minded politicians who they would fund, and circulate in and out, rotating the candidates who would all comply with their common agenda.
Laws can never and should never try to take the place of what We the People can and should do. It is up to laws to guard our freedoms but it is up to We the People to exercise our freedoms. That includes throwing corrupt politicians out and keeping them out and vetting and electing non-politicians who are willing to serve for America’s good, not their own.
