I think you’re right. Too many Jew haters in her party to have picked Shapiro. It’s all speculation but I subscribe to the opinion that she chose that goofball Walz because she couldn’t tolerate having anyone who might upstage her
Harris was all set to nominate Shapiro until the core of the Dems (Leftoid Islamophiles) grumbled. In a last minute panic she (her DS handlers) plucked weirdo Walz from obscurity. Brashear might have carried them over the line (ugh).
