Does Tim Walz's Vote History Help the Ticket?

On Tuesday, Vice President Kamala Harris made her running mate announcement official by selecting Governor Tim Walz (D-MN) over Governor Josh Shapiro (D-PA), the latter considered more moderate and pragmatic. It's a bit early to gauge what the polls say about Walz, though released ones indicate an overwhelming majority of voters don't know enough about him to have an opinion. That being said, Walz is a fellow far-left radical, so it's worth wondering if the more voters hear about him, the less popular the ticket will become. As a two-term governor, there's also Walz's own vote history to look at.
