You can lead a horse to water....
A lot of these problems can be fixed if YOU run for a seat on your local school board. Get active.
It takes only a few bucks and some paperwork to get on the ballot. In some cases, a few friends with large families and a small budget is all that is needed to run a successful campaign due to low voter turnout in these elections.
Then go to your next local Republican or Tea Party meeting and introduce yourself and tell them why you are a conservative candidate they might be interested in supporting. If you are a member of a large church, let it be known you running for the board. Gather support from registered voters.
If you don’t get elected, at least you have scared the hell out of your liberal board member opponent and his cronies. Whether you get elected or not, in some liberal areas a conservative candidate can expect death threats, cross burnings, toilet papering, slandering gossip, and maybe an occasional 3 a.m. drive-by horn honker. But do not let them intimidate you.
If you fail the first time, run again. This time tell them you are a moderate or moderately conservative. It worked for the RINOs and democrats. But get elected, otherwise nothing is going to change.
