Sure, everyone can make a mistake--that happens to all of us.
But when a person continues to make one error after another, those errors can no longer be called mistakes--instead those actions are choices.
Even if we were to believe that Trump truly believed the vote was fraudulent in November, once that fraud was proven wrong, Trump's choice to continue to spread the election fraud narrative and brand it Stop-the-Steal, was an abuse of power--it was one step in his incitement series of choices, choices that set the stage and incited the deadly Janaury 6th Insurrection at our nation's capitol. Trump himself staged a coup, and then for hours, sat back and watched it happen. He abused his power with incitement step after step.
Further, it appears that he targeted the second and third in command, Vice President at the time Mike Pence and Speaker of the House Nancy Pelosi. These are clear insurrection moves. When Trump heard Pence was in danger, he not only didn't act, but he inflamed the deadly insurrection more by tweeting out derogatory words about Pence. The House Managers clearly showed that the insurrectionists were following Trump's tweets, doing as he directed, and looking to harm and kill Mike Pence and Nancy Pelosi.
It is clear that Trump incited a deadly insurrection with choice after choice. It is the Constitutional obligation for every senator to convict Trump. If they do not vote to convict Trump, they are showing infidelity to their Oaths of Office. It is clear, Trump abused his power. It is clear, Trump acted with infidelity to his Presidential Oath of Office. it is clear that Trump incited a deadly insurrection. It is clear that Trump put the American people, our public spaces, and our government in danger. Convict trump.
