Elon Musk gave his personal political committee, America PAC, more than $76 million in the first two weeks of October to boost Republicans in the final stretch of the midterms, according to a pre-election report the PAC filed Thursday evening with the Federal Election Commission. The group spent nearly $43 million in the first two weeks of October, and entered the campaign’s last leg holding nearly $47 million in cash. The Texas Senate race dominated the new spending.
