Elon Musk has spent 276 million dollars backing organisations that support right wing candidates ahead of the US midterm elections. A report on his political giving detailed the sum, which went to groups working to boost Republican hopefuls. Few individual donors match that level of spending in a single election cycle. Musk has grown steadily more involved in American politics in recent years. Republican campaigns are counting on his financial backing in the closing stretch before voting day. The actual effect of the money will only be clear once the results are tallied.
