I always assumed he had to deal with a congress of the other party but i just checked and that is false. Democrats had huge majorities in both houses!
During his first two years dems held the senate 61-38 ( 1 indy} and the House 292-143
His next two years it was 58-41 ( 1 indy) and 277-158.
He prolly could have made a lot of changes if he wanted to, but chose not to. I like that. In particular, he didn't start any wars though the bankers and news media tried to push him into a war with the staged Iran hostage crisis of 1979. He was NOT a weak president. He stood up to the war profiteers.
Jimmy Carter was a horrible President. I lived through him. We had interest rates at 22%, that was a typical home mortgage rate. Inflation at 10%. Unemployment extremely high. The sentence back then was that the unemployed in this nation could hold hands and reach across it. The very first thing he did was reduce the amount of mortgage interest deduction one could deduct which cost the middle class a lot more money in income tax. Democrats got to where they hated him. He was very weak on foreign policy. The icing on the cake 50 American hostages held by Iran for 18 months that made the nightly news every night. Then a failed rescue attempt. Really the only people I have ever heard speak kindly of Carter, where teachers, and that's because they got a raise, while the students they taught were having to go to school with holes in their shoes. Everyone in the private sector suffered under Jimmy Carter.
Which resulted in this:
But Jimmy Carter may get beat here with Donald Trump in office. Even though Republicans have the majority in both houses, Trump & his supporters have made a lot of enemies there. Republicans in the Senate and the house certainly have no loyalty to Trump. Senate & House Republicans didn't want Trump, and they have often made that very clear. Trump also has been campaigning on several things that Republicans would never approve of. Undoing existing trade agreements, the wall, mass deportation, etc. etc. Hillary Clinton is now 1.7 million votes ahead of Trump, so his mandates are down the toilet.
IOW--Donald Trump may be our first lame duck President before he's even sworn in, and that will result in the next Jimmy Carter type Presidency.
