How so? He had a Democratic majority in Congress his entire term. Filibuster wasn’t as widespread as it is now.
He micromanaged his staff, and never got a good grip on the sausage making process in Washington. He was also more in bed with Evangelicals than people notice today. His sister is a pretty big reason why Evangelicals are so politically active these days.
He’s a pretty great human being all round. He sucked as President, and it has little to do with the GOP.
