But how much did the House seat cost them?
When we put the question to our Facebook readers earlier this week, their answers were philosophical and sometimes cynical:
"My entire paycheck," said Victor on Redwood City-Woodside Patch Facebook.
"For this year's election, I'd expect the cost to be zero," said Bob on Menlo Park-Atherton Patch Facebook.
"No matter how much it cost, Jackie has given back to San Mateo," said Peter on San Carlos Patch Facebook. "Speier was shot at Jonestown on a fact-finding mission when she was a young aide. Jackie has worked tirelessly for our best interest and she is a great!"
In terms of dollars and cents, Eshoo raised $1,489,802 during the 2012 election cycle, according to MapLight, a non-profit that tracks money in politics. Speier raised $969,474.
This compares to the average House member, who raised $1,689,580, or $2,315 a day during the same election cycle, according to MapLight.
