But Not in the Palmetto State
From The New-York Times November 27, 1860:
BALTIMORE, Md., Monday, Nov. 24.
An association calling themselves the “Southern Volunteers,” displayed the Palmetto flag from their place of meeting to-day. A large crowd was attracted by the novelty of the thing, and the flag was greeted with groans and hisses from the crowds and with plaudits from the Volunteers. Capt. JONES, of the bark Isabel, also displayed the Palmetto flag from the mast-head of his vessel this morning, when all the ships in the vicinity immediately ran up the stars and stripes.
This diversity of views seems to make sense given the results of the 1860 Presidential Election. The Southern Democrat Breckinridge won 45.9% of the vote; Bell, of the Constitutional Union Party, came very close at 45.1%.
Douglas (6.4%) and Lincoln (2.5%) were at least on the ballot in Maryland.
