Being flagged as "Not suitable for all advertisers." does not mean your videos are blocked in any way. You simply do not earn money from page views from advertisers, which is perfectly reasonable if you start getting into politics.
Indeed, there's a reason why tv networks have for decades chose "safe" tv that can be monetized and for a very long time chose to evade politics, see Smothers Brothers. It's easier to coax revenue from largely apolitical media.
