Democratic state Sen. Steve Gallardo announced Tuesday that he will drop out of the race for Congress in the 7th District, leaving only two major candidates competing for the heavily Hispanic seat -- Maricopa County Supervisor Mary Rose Wilcox and former state Rep. Ruben Gallego.
He also announced that he will be running for the seat on the Maricopa County Board of Supervisors currently held by Wilcox.
This all started when Congressman Ed Pastor announced that he would retire after this term in Congress, opening up that race.
Wilcox, Gallego, and Gallardo announced their intentions to run for the CD7 seat.
That, in turn, led to Marie Lopez Rogers, mayor of Avondale, and Anna Tovar, Democratic leader in the state senate, announcing their intents to run for Wilcox' seat on the Maricopa County Board of Supervisors.
Gallardo is a good senator and a good candidate, but the CD7 race quickly became a two horse race, with Gallego and Wilcox garnering most of the big-name endorsements and almost all of the campaign contributions.
Last week, Tovar announced that she was withdrawing from that race and not seeking any any office this year. opening up that race for another entry.
This close to the filing deadline, there probably won't be any more serious dominoes falling in these races, but I've been wrong before.
In other words, keep paying attention.
