What two issues were used by jefferson and madison to discredit the Adams administration?

One issue between the men was the Alien and Sedition Acts. Jefferson believed that the acts themselves leaned toward establishing a dictatorship, which was out of the question and against what they had fought for.

There was also Adam's last minute appointment of federal judges. This selection of "midnight judges" caused a huge rift between the two.

Thirdly, the Kentucky Resolution was supported by both Jefferson and Madison.
