When I lived in Marin County—just before the 1994 Presidential election I worked for Republican candidates. Every time I put up a “Vote Republican” sign, it was taken down immediately—no matter what time of day or night—no matter how inaccessible I made it. EVERY SINGLE ONE was snatched down as soon as it was put up.
Heck, when we put out our mclame/palin yard sign in Brevard County florida, it was gone in broad daylight within an hour. I figured there wasn’t much point in putting another one out after that. Unless we wanted to try to catch the assclown who didn’t believe we had any first amendment rights. (The ones NOT “granted” to us by the govt.)
