WASHINGTON _ Arizona Democratic Rep. Ruben Gallego has decided not to run for Senate against GOP Sen. Martha McSally, according to a source with knowledge of his decision.
Democrat Mark Kelly, a Navy veteran and former astronaut, is already in the race and has proven to be a strong fundraiser. Kelly is married to former Rep. Gabrielle Giffords, D-Ariz.
McSally is among the more vulnerable senators running in 2020. Inside Elections with Nathan L. Gonzales rates the race a toss-up.
Speculation has swirled around Gallego running for the Senate for years. First elected in 2014, he represents a solidly Democratic Phoenix-based district. Last year, he won his re-election bid for the House with approximately 85 percent of the vote.
Gallego's spokeswoman confirmed his decision to Roll Call.
