Tonight, Vice President Joe Biden will be facing off with Republican vice presidential candidate Rep. Paul Ryan (R-WI). But while Ryan is willing to debate with Biden tonight, there is another man he’s been running from.

See, Ryan has an unusually strong congressional challenger this year named Rob Zerban. Zerban is a successful and socially-conscious businessman who also has been involved in the community and local activism for years. He’s well-liked, and polling shows that Zerban is within single-digits of Ryan.

Their policy differences couldn’t be more stark, especially on one of the most important issues: protecting Medicare. Ryan is the author of the “Medicare For None” plan that would turn the entire program over to private insurers, while Zerban is campaigning for Medicare For All.Ai?? In his recent television ad, Zerban criticizes RyanAi?? for spearheading this plan to end Medicare, and he promises that he will “never cut Medicare benefits. Ever.” Watch it:

But Ryan has refused to attend a single debate with Zerban. From his perspective, if he just ignores Zerban, voters won’t be able to learn about the alternative. The Republican congressman has committed, however, $2 million to a huge ad buy to defend his congressional seat.

We’re not willing to stand by and let Paul Ryan dodge his responsibility to give voters a fair choice. Chip in $3 to Zerban’s campaign and help him educate voters about the fact that they have a great alternative to Ryan in November.
