The web search results mention Ohio's economic development efforts and attracting talent, but none of the provided snippets confirm a specific, current 'marketing blitz' aimed at L.A. residents. The evidence is general regarding Ohio's efforts, not specific to a L.A. targeting campaign.

One web search result mentions a program offering up to $15,000 for recent STEAM graduates in Hamilton, Ohio, and another mentions a general initiative offering up to $15,000 for home purchases in Topeka. However, there is no single source confirming a blanket incentive of 'up to $15,000 per worker' across the board from the state.

Two web search results mention significant financial incentives and job creation related to Anduril's move to Columbus, Ohio, citing a $310 million grant. However, neither source specifies the exact figures of '4,000 jobs' and '$910 million' as a confirmed, single total package. The evidence points to large investments and grants, but the specific cumulative numbers are not independently corroborated.

One web search result states that 'Approximately one-third' considered leaving, while another mentions 'One in three' in the claim. The evidence is consistent in suggesting a significant portion considered leaving, but the exact 'one in three' figure is only presented in the claim's context and not strongly corroborated by a second independent source.
