2016 Election: These Senate races could determine who controls Congress’ upper chamber
If Democratic candidate Hillary Clinton wins the presidency, she could find herself with a very welcome gift on Election Day — a Democrat-controlled Senate.
Several Republican senators up for re-election have been fighting for their political lives since Republican candidate Donald Trump fractured the party with his controversial campaign.
There are 34 Senate seats up for grabs on Nov. 8. Ten are held by Democrats and 24 are held by Republicans. Democrats need to pick up four seats to take control of the upper chamber of Congress.
And there's a strong indication of that happening. Up to seven Senate seats could go to Democrats, according to the Cook Political Report.
These are the Senate seats that are in jeopardy in the 2016 election.
