Midterms Speed Read: All You Need to Know About Tuesday’s Vote

(Bloomberg) -- The 2018 midterms are the most closely watched, most expensive and most fretted-about congressional elections in memory. They’re always about the one person not on the ballot -- the president -- but never more so than this year.

Democrats are expected to take control of the House of Representatives but fall short in the Senate. Then again, Democratic candidate Hillary Clinton was expected to beat Donald Trump in 2016. The party’s despair over a second loss to Trump would be immeasurable.

With the campaign entering its final hours, here’s the state of play:

1. Political pros expect. . .

2. Yet Democrats are suddenly nervous

3. If Democrats end one-party government, look for. . .

4. Markets might be OK with a Democratic takeover

5. Democrats can stymie Trump domestic policy

6. Democrats cannot stymie Trump foreign policy

7. Special Counsel Robert Mueller is still out there

8. The I-word: Impeachment

9. And what if it is a repeat of 2016?

10. Either way, 2020 begins immediately
