Two grids on the same template. The first is empty - print it, fill in each cell with a one-line note while you revise. The second is a worked example to check yourself against.
Each cell asks one question: does this row strengthen the column quality (mark +) or weaken it (mark -)? Then add a one-line note saying why. The plus and minus columns are deliberately not pre-printed - your judgement is the work.

| Check+ - | Constitutional basis | Bit recently | Depends on party control | Checks domestic power | Checks foreign policy | President can bypass | Effective overall |
|---|---|---|---|---|---|---|---|
| Congress: legislation + the purse |
+Article I: all legislative power and the purse. | +Obama's agenda hit a wall after the 2010 midterms. | +Unified government passes; divided government blocks. | +Lasting domestic change needs statute and money. | -Funding wars is politically hard to refuse once troops deploy. | +The pen-and-phone presidency - DACA, climate rules, Paris - until the next president reverses it. | +The strongest check - when the votes are there. |
| Impeachment | +The Constitution's removal mechanism - House impeaches, Senate tries. | -Two impeachments of Trump 1, two acquittals on party lines. | +Conviction needs two-thirds of the Senate - impossible without the president's own party. | -A deterrent at most. | -The Ukraine impeachment was foreign-policy conduct - and failed. | -Cannot be bypassed, only survived. | -A partisan formality in a polarised Senate. |
| Supreme Court |
+Judicial review - the Court polices executive action. | +Executive orders from both parties blocked in the courts. | +Appointments politics decides how hard the check bites. | +Orders and agency action regularly halted. | -Courts defer heavily on national security. | -Rulings bind - but a president picks the future Court. | +Real - and increasingly shaped by the presidents it checks. |
| Federalism and the states |
+The 10th Amendment reserves powers to the states. | +Sanctuary-city resistance in both Trump terms; red-state resistance under Biden. | +Resistance maps onto which party holds the statehouse. | +States can refuse cooperation and set divergent policy. | -No state role abroad. | +Funding conditions pressure states - the federal lever is money. | +A growing check in a polarised federation. |
| Midterms + public opinion |
-No constitutional text - pure politics. | +2010 transformed the Obama presidency overnight. | -Works regardless of party - the out-party usually gains. | +A lost chamber ends the legislative presidency. | -Voters rarely vote on foreign policy. | -No president has found a way around the calendar. | +The most reliable check in the system. |
| War powers | +Congress declares war; the 1973 Resolution adds reporting rules. | -Routinely ignored - the June 2025 Iran strikes the latest case. | +Congress objects loudly only to the other party's wars. | -Not a domestic check. | -The clearest failure: presidents conduct war on their own authority. | +Notification and finesse substitute for authorisation. | -The weakest check on the grid. |
