What was Haynes point of view in the Haynes Webster debate

The Webster-Hayne debate was a debate between Senators Webster of Massachusetts and Hayne of South Carolina in 1830.  The debate was about two interlinked items: the protectionist tariffs of the 1820s, and the South Carolina nullification crisis that resulted from South Carolina's objections towards a nationwide tariff against foreign imports.
Haynes, as a representative of South Carolina and the broader Southern interests, was against protective tariffs.  The South lacked factories to make goods domestically and overall, the South imported more goods, which were subject to tariffs.  Because the nationwide tariffs did not benefit South Carolina, South Carolina decided to state it had the right to nullify (cancel enforcement) of the nationwide tariff laws in the 1820s.
Hayne's position in this debate was to continue to defend South Carolina's role by trying to eradicate the tariff and to emphasize the doctrine of state's rights, in which states have the right to defend their economies from nationwide laws.
