This portrayal of president andrew Jackson reflects the opinion of some of his opponents what?

Executive Branch had become too powerful

Explanation:

By the time the founding fathers established united states government, they swore that this government wouldn't turn into monarchy. They believe giving full power of a the government to the hand of one man will create a huge risk of turning the country into tyranny. So, they separate the government into executive, legislative, and judicial branch.

Because many of Jackson' political opponent saw his action as Tyrannical, They often portray Andrew Jackson as a King. At that time, portraying government official as a king was regarded as an insult since it's basically say that you're someone who abandon democracy because of your greed of power.

These opponents believe that Andrew Jackson has made the executive branch have too much influence over the legislative and judicial branch, making him almost had absolute power in the government.
