Joe Biden's choice of running mate, which he promised would be a woman, is likely to have significance beyond election day.If his ticket wins, she'd be the first female vice-president, and possibly be the presidential candidate in 2024.

One can imagine Democrats have greeted the news of Justin Amash's third-party presidential run with concern, believing they've already suffered through one third-party nightmare in the last presidential election and don't need another, writes Keith Boag.

Donald Trump likes to say he feels like a "wartime president" battling an "invisible enemy," as though he were in command of the fight against COVID-19 in the U.S. However, as Keith Boag explains, it's often the governors and Congress making key decisions that could decide the outcome of the crisis.

No country has invested as heavily as the U.S. in the idea of itself as a land where freedom to pursue opportunity is paramount. But in a time of crisis, that creed can stray into the desperate territory of "every man for himself," writes Keith Boag.

Trump will have some advantages for the general election that could keep him in the Oval Office for another four years. Then again, there are ample signs he is in trouble.

The campaigns of three candidates who have withdrawn from the Democratic nomination for the U.S. presidency were important parts of the Dirtbag Left's strategy for electing Bernie Sanders. On Super Tuesday, the group's earlier excitement appears at best premature.
