For me, Scott Walker and Ted Cruz are at the top of the list as possible Presidents to get the US back on track.
Just remember Jeremiah 17:5. It may certainly be that Walker and Cruz have character that is superior to FDR, but they are up against a machine that wasn’t around in FDR’s day (but which FDR did promote heavily); and we do not presently have a British ally as strong as it was in those days nor leadership there of the caliber of Churchill. Even worse, the private morality of the populace is heavily degraded. And even with the ravages that the Federal Reserve was starting to wreak, the dollar was worth far more then than today, as was the pound sterling.
