I did not say that would happen, I said could happen, maybe your right, he will do a fine a job and everything will be great, but I have my doubts.
If you don't think a President can make a big mistake that cause real damage, let's examine one mistake a President made, that Trump thinks is a mistake, the Iraq War. Bush the US would find WMDs, Cheney said fighting would end in 6 months and that Iraq would be a functional democracy in short order, none of that happened and Bush brushed off any criticism as "liberal bias" and guys like Sean Hannity said it was the patriotic duty to support the President in a time of war, so a lot of people gave him a pass. So a lot of Americans died in that war, a lot of Iraqis died in that war, a lot money was wasted on that war and it created a power vacuum that helped create ISIS and now Sean Hannity is promoting the same attitude towards Trump that promoted with Bush, so does being part of the Republican base means giving a free pass to Republican Presidents? If Trump makes a similar mistake, does he get a free pass?
