I think the last 12 years are the most important, the rest is just history, but history that brought you to this point. The Obama presidency and the strength of not just African Americans, but other minorities in the democratic party means there is no going back. The old days of compromising with racism and bigotry because elements of it permeated each party are over, the two sides are now lined up on the essential historic American issue. The real fight for a better society has begun and the state of political stasis is over for as long as democrats are in ascendency.
Nobody is perfect, I have a bone or two to pick with Trudeau myself and I'm a liberal party member and a political party membership is pretty rare in Canada, compared to the USA, we therefore have a louder than usual voice. I think the government fucked up the covid response by not starting domestic vaccine production early, they should have known the current vaccine situation would arise and there are other issues I don't agree with too. For me Justin is the best option, I don't like Tories or their policies and the liberals are running so left it's making the NDP irrelevant.
If you look at the totality of the Biden agenda, there ain't a lot for an intelligent informed person to disagree with, considering the state of the electorate and the fragility of the country's democracy. After four years of Trump and the republicans abject failure, fascism, lunacy and the fact the republican party is coming apart at the seams, that they still have a very good shot at taking the house in 2022, is simply astounding. The republican party should be extinct by now or circling the drain and would be, if not for racism and white tribalism.
