1. Where are you getting these data and predictions?

2. Agreed with you here.

If Dems can keep their losses at a minimum (I'd honestly be happy if it's a net 0 this November, estatic if we actually gained seats), the Senate map in 2020 is as ugly for Republicans as this year is for Democrats. But really, I like the Democratic Party's chances of at least breaking even this year.

3. Breaking even is a likely scenario in 2018

Democrats are going to pick up AZ and NV, TN if they are lucky.
Democrats could lose IN and ND, FL and MO if they are unlucky.
Trump state Democratic incumbents in MI,MT,OH,PA,WV, and WI will definitely get re-elected.
