德桑蒂斯將在馬斯克的地盤上宣佈啟動總統競選
據多家美國媒體週二援引消息人士報道,美國共和黨熱門候選人、佛羅里達州州長德桑蒂斯將在週三宣佈正式啟動競選活動——而且是在網紅富豪馬斯克的陪伴下。
在週二通過視頻出席公開活動時,馬斯克表示,他週三將在推特平台上採訪德桑蒂斯,並表示共和黨新生代紅人將“宣佈一個大消息”,這將是社交媒體歷史上從來沒有過的事情。
據知情人士透露,馬斯克對談德桑蒂斯的活動將在語音交流平台Twitter Spaces上進行,時間暫定為美東時間週三傍晚6點。根據日程,德桑蒂斯還將在週三晚間做客福克斯新聞的專訪,並在邁阿密的酒店舉行競選籌款活動。
馬斯克也在週二強調,他還沒有背書任何特定候選人的計劃,但對推特成為“某種市政廣場”的用途很感興趣。他同時還意有所指的表示,希望美國白宮裏能有一些“相對正常的人”。
值得一提的是,馬斯克本人在2020年大選中把票投給了拜登,但之後常常在公開場合批評拜登。在上週接受媒體採訪時,馬斯克曾表示他現在只希望“能有一個正常人類”來領導這個國家。
