Emilys political affiliation

My Aunt Emily passed away recently. Going through her effects I ran across the following button:

Attached to a note referencing a supposed but disputed quote from Nostradamus:

In 1555, Nostradamus wrote:
"Come the millennium, month 12
In the home of greatest power,
The village idiot will come forth
To be acclaimed the leader."



 Can you guess her political affiliation?
