Former Arizona Attorney General Grant Woods made an announcement on Friday. He will not run for the open Arizona United States Senate seat in the 2020 election.

Since last September, Woods had been considering a run for the U.S. Senate. After being frustrated with Donald Trump’s presidency, Woods switched his registration to Democrat. During his time as Attorney General and Senator John McCain’s chief of staff, Woods was registered as a Republican.

Woods had originally considered running to unseat Republican Senator Martha McSally, because he believed that she enables President Donald Trump. Woods believes that he can more effectively combat President Trump and his enablers while not running for the Senate seat. While he is committed to helping Democrats win seats, he believes that proving he is liberal enough for all Democrats would not be an effective way to help the cause.

Woods was not the only Democrat who is rumored to be considering a 2020 Senate run. United States Representative Ruben Gallego and husband of former Representative Gabby Giffords, Mark Kelly, are both rumored to be considering joining the race for this Senate seat.

Most expect that Senator McSally will run again, but she has not made any official moves to join the race yet.
