Like any politician in the last 145 years in the US has upheld the Constitution of these United States or their state constitutions. Better to pander to the electorate on questionable constitutional, and Constitutional, grounds. His foremost duty is to hold the office of the executive branch of the state of Florida and stay within his limitations as outlined in that document. Perhaps Dr. Keyes could get a bill like this passed in his state if he's so concerned about it? Whichever state that happens to be at the moment? Oh, I forgot, he's not been elected to office has he?
Wow. His first job is to hold onto his job, eh?
He is not 'staying within his limitations as outlined in that document', he is ignoring his duty.
