Here is a compact table listing all of the Senate candidates.

The current breakdown of the Senate is as follows (where we count the two independents as Democrats):

• 10 Democratic seats up for reelection in 2016 and 36 seats not up, for a total of 46 seats
• 24 Republican seats up for reelection in 2016 and 30 seats not up, for a total of 54 seats

In a reversal from 2014, the Democrats will be playing offense, trying to pick up at least five seats (or four seats and the vice-presidency) in order to reclaim control of the Senate. As they do so, there are several pieces of good news for them:

• The party has had enormous success this year in recruiting top candidates, not only in states where the Democrats' chances are excellent, but also in states where their chances are only middling. By contrast, outside of Nevada, the Republicans have struck out with their preferred candidates.
• There is only one Democratic-held seat that is presently in play (Nevada). In contrast, as many as 16 Republican-held seats are or could be in play, with at least seven of those being in significant danger (Wisconsin, Illinois, Indiana, Pennsylvania, Florida, New Hampshire, and Arizona, in roughly that order).
• The Republicans are defending so many seats they will almost certainly be compelled to do some triage and declare some races to be lost causes.
• Presidential election years favor the Democrats, as they bring more minorities, young people, and single women to the polls.

The news is not all bad for the Republicans, however:

• The 2016 election is not a mirror image of 2014. In that election, the Democrats' "in play" seats were in very red states like Alaska and Montana. This year, the Republicans' "in play" seats are largely in purple or light blue states like Ohio, New Hampshire, Florida, and North Carolina. In other words, the Republicans have an easier position to defend in 2016 than the Democrats did in 2014.
• The tea party's influence has waned, such that the Republicans will not be blowing a competitive race this year by getting stuck with someone like Christine O'Donnell, Todd Akin, or Sharron Angle.
• Even if they lose control of the Senate next year, the 2018 map will once again favor the Republicans, as the Democrats will be defending 23 seats in a nonpresidential year, including those in the red (or reddish) states of Indiana, Missouri, Montana, North Dakota and West Virginia. Should they wish to secure control of the Senate until the next presidential election, the Democrats will likely need a net gain of eight or nine seats this year—a very tall order.
