New Yorkers do tend to blame Hizzoner and not the President during high crime times. We don’t believe everything.
NY’ers may not ‘believe everything’, but I know from living and working in Manhattan for 15 years that Democrats/liberals get an almost exclusive pass from the local media (ex NYPost; WABC talk radio) and the vast majority of locals and communters (CT and NoNJ aren’t exactly bastions of conservatism).
Your social circle and business associates may be objective and rational thinkers , but my own experience with NYC says otherwise.
