Just curious: what does "taken a nosedive"  mean here? Was there an Andy Murray popularity poll?

As to the women quietly voting "no" for anti-mayhem, Andy Murray, the tennis star, should have perhaps taken a hint from them.  Born in Scotland, but an English resident for years, he has been loved and supported by the English.  Although he couldn't vote yesterday because he does not reside in Scotland, he made known his "yes" opinion and his popularity in England has taken a nose dive.
