The presidential election may have been at the top of the ticket in this year’s general election. But it was not the only national race that got people’s attention.

Key Congressional races have also dominated headlines. Democrats are hoping to wrest control of the House from Republicans, who currently have a slim majority in the lower chamber. Both parties have spent heavily in competitive House races this election cycle.

Two of those battleground races are in Los Angeles County. In both races, the incumbents are Republicans, but Democrats are hoping to flip the seats blue.

County’s Antelope Valley. And in District 45, which includes parts of southeast L.A. County and northeastern Orange County, Republican Rep. Michelle Steel is attempting to fend off Democrat Derek Tran.
