Signs supporting those candidates or others in the upcoming election can be displayed on OPA lots. The signs in question are not candidate signs.

Anyone in support of voucher systems or MOE is not supporting public education. 

That statement is certainly questionable as a fact.

The parents behind Worcester United are right to be concerned.

Why doesn't the group allow anyone visiting their page on Facebook to see what they post? 

If I have to look at my neighbors stupid political flags year round, I can certainly tolerate a yard sign through May 14th.  

I believe Maryland HOA Act sets time frames for political candidate signs:

(3) If a limitation to the time period during which signs may be displayed is not specified by a law of the jurisdiction in which the homeowners association is located, to a time period not less than:

(i) 30 days before the primary election, general election, or vote on the proposition; and

(ii) 7 days after the primary election, general election, or vote on the proposition.

If you believe your neighbor's political signs are in violation of the above then you should contact OPA and report the violation.

Finally, is your position that the Worcester County Commissioners should simply rubber-stamp any proposed Board of Education budget, regardless of the amount?
