Alex Lasry for Senate?

Though it is still 9 months away, I've read here on DU a few times that people seem to think lieutenant governor Mandela Barnes is a shoe-in for the nomination to take on Ron Johnson. Here in the Madison TV market I haven't seen a single commercial for Barnes, but I see commercials for Alex Lasry all the time and have for many months. I personally haven't formed an opinion on who I will vote for yet, but I like Lasry's commercials, and I'm looking forward to the primaries to hear from these two as well as the others seeking the nomination.

Most important, who can beat Ron Johnson.
