The Republicans currently hold a 53-47 edge in the US Senate. (And that, of course, is counting Angus King--an independent from Maine, who caucuses with the Democrats--as a Democrat.) But one may reasonably inquire: Just what is the Senate likely to resemble after the November 2020 elections? Well, Colorado is a likely pickup for the Democrats. Sen. Cory Gardner--the incumbent, and a Republican--may be vulnerable to a challenge (presumably, from John Hickenlooper). On the other hand, Alabama is quite likely to elect a Republican to replace Sen. Doug Jones--who merely replaced Jeff Sessions by winning the Democratic primary in 2017, and then defeating (the disgraced) Roy Moore in the general election. Of the two, the Republicans are probably in better shape, as Alabama is a deep-red state, whereas Colorado is more of a purple state (with more blue than red in it). Some other states to watch: Arizona features former astronaut Mark Kelly (D) challenging the incumbent senator, Martha McSally (R)--who was merely appointed, not elected. And North Carolina features the incumbent, Thom Tillis (R), hoping to ward off a challenge from Cal Cunningham (D). I would not be at all surprised if the Republicans were to win two of the elections mentioned above, with the Democrats taking two. How do others see it?
