What do you need to have in order to be a Federal District Court Judge?

There are almost no formal qualifications for federal judges. Article I magistrate and bankruptcy judges are required by statute to be lawyers, but there is no such requirement for district judges, circuit judges, or Supreme Court justices.

Explanation:

in mcculloch v. maryland (1819) the supreme court ruled that congress had implied powers under the necessary and proper clause of article i, section 8 of the constitution to create the second bank of the united states and that the state of maryland lacked the power to tax the bank.

gibbons v. ogden, (1824), was a landmark decision in which the supreme court of the united states held that the power to regulate interstate commerce, granted to congress by the commerce clause of the united states constitution, encompassed the power to regulate navigation.
