By how much do you regret your vote? In reality, I don't regret it. I believe having Trump be elected as president and embarass the republican party was much better than having Hindi Vance or Ron DeSanctus as presidents in the near upcoming US elections. Trump's presidency loosened the curtains and showed how useless the republican party is.
Kamala Harris is, and would have been pro-israel either way, and the pro-israel republicans in congress would have still kept their jobs and continued to make attacking for israel a priority. Nothing would have been improved had Kamala became president. All we know now is that elections are fake and gay, if it weren't so obvious, it has become more apparent.
