Was Thomas Abraham Clark a anti-federalist?

Answer 1

He cant be.

Thomas Jefferson was a Democratic Republican.

Thomas Jefferson began as an Anti-Federalist. During the Presidency of George Washington, he was a member of the 'Opposition' faction. Eventually he joined the Republican party - not to be mixed up with the Republican party that was established 1856-today. These republicans were referred to as 'Democrats' by the Federalists, who thought their ideals were more mob-rule than true republicanism. Today they are sometimes called the Jeffersonian Republicans. This even, does not quite fit, since the party underwent many changes. IE, in 1825, the two parties were considered 'Jackson Democrats and the 'Adams Republicans'. By 1829, The Republicans/Jefferson's party had become the "Democratic Republicans" (The name that still sticks today in referring to his party). The Adams Republicans had become the "National Republicans."

By 1835 or so, the Democratic Republicans had dropped the Republic and just become "Democrats". The National Republicans had become the "Whigs."

In 1850, when the Democratic Party won the Missouri compromise, a major pro-slavery battle, the Whigs lost their prominence. Most Whigs joined with several other minor parties to form the "Republicans" (The republican party of today), while some joined the Democrats.

The Republicans became a major thorn in the side to the pro-slavery Democrats, launching their first platform in 1856 focusing primarily on civil rights.

So to answer your question more succinctly: He was an anti-Federalist/Opposition/'Republican' (In the sense of what became later the Democratic Republicans or Democrats or 'Jeffersonian Republicans', not modern Republicans.)
