This is a contested question, so I'll lay out the structure rather than pick a side. Several things determine how much an administration can do on its own, and people disagree about which ones matter most.
The main formal limits are Congress, which controls spending and writes most laws; the courts, which can block actions as unlawful or unconstitutional; and elections, which decide who holds power next. Agencies also act through rules and executive orders, and those are often challenged in court. Much of what happens in a given period depends on how these checks are working at the time, and on whether the House and Senate are controlled by the same party as the White House.
Beyond the formal rules, people point to different explanations. Some argue that a president's party in Congress rarely breaks with him, that voters are divided and polarized, or that the public has limited attention for slow-moving policy. Others argue that the real problem is the economy, inequality, or specific policies that they believe hurt people, and that the system is working as designed to respond to voters.
If you tell me which actions or policies you have in mind, I can look at the specific legal authority behind them, what courts have said, and what the record shows. What would you point to first?
