Since the 1990s, which political parties have generally supported free trade and which have generally oppose it? Why?

Democrats have been opposing free trade in its compete sense while the republicans have been for it.

Explanation:

The American left is economically in the socialist front while it is liberal in its civic front and is broadly represented by the democrats however, none of these classifications hold much weight but it is the general trend.

The conservatives also tend to be more into the free trade and capitalism and form the republican side of American politics and the red states.

These people are the ones that believe in free trade because they believe that US is the land of  capitalism and it must flourish unaided and it w ill help the community of people.

1) checks and balances- this idea is implemented in the constitution to ensure that no one branch of the federal government gains too much power. for example, the legislative branch(congress) can approve a bill that will then be sent to the executive branch (president). if the president does not like the bill or thinks that it violates the rights of citizens, he/she can veto the bill. vetoing the bill stops the bill from becoming a law. this check on power ensures that congress makes laws that do not violate the rights of citizens.

2) anti-federalists do not want to ratify the constitution unless it includes a bill of rights. the anti-federalists are worried that the constitution gives too much power to the federal government. having a strong central government caused problems when the us was still part of great britain. this is why the anti-federalists are fearful of this type of system.

3) federalists want a new constitution passed because it will fix america's weak political structure. before the us constitution is implemented, the constitution being used is known as the articles of confederation. this constitution has an extremely weak central government, allowing for disunity among the states.
