6 Key 2018 Midterm Senate Races to Watch
Arizona
The 2018 midterms represent an opportunity for Arizona Republicans to elect a pro-Trump senator to replace Republican Sen. Jeff Flake, who is not seeking re-election and has had his fair share of issues with Trump in the past.
However, the contest is currently ruled as a toss-up by Real Clear Politics as Republican Rep. Martha McSally holds a slim 45.3 percent to 45 percent lead over Democrat Rep. Kyrsten Sinema, according to Real Clear Politics average of polls.
No matter which of the two major party candidates wins, history will be made when either of the two are elected as Arizona's first female senator.
Sinema is endorsed by groups like Planned Parenthood and the LGBT activist group the Human Rights Campaign, while McSally is backed by Trump, who won the state with over 49 percent of the vote in 2016.
