journalist horace greeley founded the liberal republican party and he ran for the u.s. presidency in 1872 but died before the election results were finalized.

Explanation:

The two independent clauses "Journalist Horace Greeley founded the Liberal Republican Party" and "he ran for the U.S. presidency in 1872 but died before the election results were finalized" are connected by "and". When connecting two independent clauses with a coordinating conjunction (like "and"), a comma should be placed before the conjunction. So we add a comma before "and".

Answer:

Journalist Horace Greeley founded the Liberal Republican Party, and he ran for the U.S. presidency in 1872 but died before the election results were finalized.
