The races in Iowa and North Carolina remain particularly close at this point, and Democrats will probably need to win at least one of those to take the Senate.
Their chance of doing this will be increased significantly if Biden defeats President Donald Trump in these states
. At this point
, that looks quite possible
Biden leads Trump in all five of the states where Democrats have their best Senate pickup opportunities
. Those advantages tend to be fairly close to the lead Democratic Senate candidates have in those same states
: 3 points in Arizona
, 13 points in Colorado
, 1 point in Iowa
, 15 points in Maine and
2 points in North Carolina
. The average difference across these states is just
, with Maine being a notable exception to the overall trend
Likewise, the one seat Republicans are favored to pick up (アラバマ) shows the same premise: the party winning in the presidential race is leading in the Senate race as well.
Indeed, the Democrats’ best chance of expanding the Senate map is in a state where Biden has been making clear gains against Trump: ジョージア.
Biden now holds an average 2-point edge over Trump in the Peach State, where there are two competitive Senate races. In the race for a full six-year term, the battle between Democrat Jon Ossoff and Republican Sen. David Perdue has grown quite tight in recent weeks. In fact, the two are tied in an average of polls.
The complication is that it isn’t enough just to get the most votes in Georgia. You need to win a majority to avoid a January runoff. With a Libertarian candidate polling at 2% に 3%, it’s possible that no candidate reaches a majority.
The better Biden does in Georgia, the better shot Ossoff has of avoiding a runoff.
(Georgia’s other special Senate election is very likely to head to a runoff
, with multiple Democrats and Republicans running in what is known as a jungle primary
Beyond these aforementioned states, Democrats are down 4 そして 3 points in Kansas and Montana, それぞれ. Those are small enough Republican leads that the Democrats could win in these states, but with Trump ahead in both, it’ll be tough.
One thing that could make a difference in all these Senate races is the rising number of coronavirus cases nationwide
. に every single one of the states with the best chance of a party picking up a seat
, cases are climbing upward
Cases are rising particularly quickly in Iowa
, where Republican Gov
. Kim Reynolds has refused to institute a mask mandate
. This is a state where Biden’s advantage seems to have been widening somewhat in the last few weeks
, along with Wisconsin
(where cases are also rising
). Although Wisconsin doesn’t have a Senate race this year
, Iowa does
As I pointed out Thursday, Trump seems to be doing worse in communities where Covid-19 deaths are higher
That could make the difference in a state like Iowa in the presidential race, which could in turn shift the Senate race — one that ultimately could determine control of the US Senate.
