Well your wait for a vaccine is probably about to get a hell of a lot longer because I don't think anyone, D or R, expects Pres Biden to put America or American citizens first on this or any other issue. As far as COVD goes the left has checked out. Pres Trump can longer be blamed and so there is no more blame. The MSM went from [correctly] chastising Pres Trump almost daily over his response, to taking the attitude under Pres Biden that 'well its a tough job so lets cut him some slack, a lot of slack'. Hell, we never even got our desperately needed nation wide mask mandate - he never even tried to come down hard on belligerent Republican Governors and their deadly agendas. So if the question is 'Will Pres Biden put Americans at risk by cutting our vax supply in order to give it to Mexico' I firmly believe the answer is a huge yes. And we can be sure that a deal will be made that benefits the DNC on this one. It will probably be donation but there will be some negotiation. I imagine they'll use lots of, uh, 'humanitarian' language in order to get the Mexican President to ease up on the enforcement of his south border aka the gateway from South America to the USA. Of course you know they wont actually come straight out and say this but it will be there in some very deeply buried embassy memo, and in the coming months we'll see the results as the illegal influx figures rise and the caravans trend again.
