Quick Question on Tax Cuts

Voters were clearly angry. It’s not clear to me, however, that this anger had as its root cause the threatened cessation of tax cuts for the wealthiest Americans. Was there really a ground swell of support for a return to trickle-down economics? I know that everyone wants to make sure that if he or she is suddenly discovered by Ron Howard or Bill Belichick he won’t be victimized by high taxes … but was that really what pushed Democrats out of office? Is there really a mandate for keeping those tax cuts?
