Public opinion was very much in favor of the war in Afghanistan after 9/11. Maybe not so much Iraq, but it's hard to blame Bush squarely for those wars when they had bipartisan support.
Bush is done doing damage to our country, and might actually be considered a voice of reason compared to today's Republicans.
It's definitely already Trump, and he's not even done doing damage yet.
Even if Republicans elect someone who is identical to Trump in his words, views, and actions, that person would still be better for the country than Trump. It's critically important for the justice department to hold him accountable for the insurrection and trying to overthrow our democracy, or it WILL happen again.
