Colorado Senate candidate Andrew Romanoff (D) joked Tuesday afternoon on Twitter about making financial sacrifices to fund his campaign.

He said:

This morning a radio host asked me, "Are you going to sell your dog?" Absolutely not! But I am willing to rent him for a while ...

Romanoff, the Speaker of the Colorado House of Representatives, seeks to defeat Sen. Michael Bennet (D-Colo.) in the Democratic primary. He recently sold his house in Denver in order to loan the campaign $325,000. Bennet's fundraising, meanwhile, has totaled $7.5 million.

The primary is August 10.
