2018 US Senate Races

In the US Senate, Republicans now have:

52 seats; Democrats have: 48 seats — counting the 2 independents (Bernie Sanders and Angus King who caucus with Democrats).
To FLIP the Senate in November 2018, Democrats need to NET a total 3 seats, meaning they will need to win 3 more seats than they lose.   Now, having to gain a total of 3 seats does not sound like that daunting a target.  Unfortunately, gaining even the small net of 3 seats will be extremely hard to accomplish in 2018 simply because of Mathematics! 
Of the 33 Senate seats up for grabs in 2018, only 8 are held by Republicans trying to defend their seats.  Simply by the luck of the draw, the Republicans are mostly in safe states for the Red team.  Only Jeff Flake of Arizona, and Dean Heller of Nevada are in significant danger of losing their seats. And both have started dancing away from Trumpism in preparation for their tricky re-election bids in 2018.    
In contrast, of the total of 33 contested Senate seats in 2018, 25 are DEMOCRATIC senators trying to defend their seats.  And, to make it even more bleak, many of these Senators represent RED states and are extremely vulnerable in 2018. The good news is that most of these senators generally have to be great politicians just to win and keep their seats in these red states.  Hopefully,  those skills and instincts for winning close close elections will see them through. 

To reiterate, Democrats would be doing really, really well just to keep the Republicans current advantage of 2 from increasing any further.
