Bush was a decent guy. But he was terribly wrong on a number of issues.
He was a big spender.
He gave up too soon on cutting taxes permanently, instead of allowing the tax cuts to be temporary.
He made some foolish mistakes with appointments, and did nothing to clean out all the clintonoids he inherited in his administration.
He was pro-amnesty.
He was far too friendly with Mexico.
He agreed to “free trade” deals that were not really free trade, but simply amounted to shipping most of our industrial jobs abroad, while doing little or nothing to get similar access to the markets in other countries.
He was, to put it briefly, just too damned nice.
You left out “He failed to go after election fraud.”
After the Florida debacle in 2000, it was obvious it needed to be done.
