In what sense is each country a two-party system?

Both have been dominated by two parties that alternate in office, but the USA excludes other parties almost completely while other UK parties win seats and can share in power.

Besides the electoral system, what practical barriers keep US third parties off the ballot and out of the debates?

Ballot access is set state by state and often demands large numbers of verified signatures within tight deadlines, and the presidential debates have a polling threshold that third-party candidates rarely reach, so they struggle to be seen even where they are on the ballot.

How do the electoral college and first-past-the-post each squeeze third parties, and why does a UK third party fare better with concentrated support?

Almost all states award their electoral votes on a winner-takes-all basis, so a third party can poll widely and still win nothing, whereas a UK party with concentrated regional support converts those votes into seats.

How do primaries entrench the two US parties in a way UK selection rules do not?

An insurgent movement can capture a major party's nomination from the inside, so it has no incentive to break away and form a separate party as UK factions have sometimes done.

Questions from this subtopic

Each one with the model answer underneath.

1
Name the two dominant parties in each country.
Model answer
The Democrats and the Republicans dominate in the USA, and the Conservative and Labour parties dominate at Westminster.
2
In what sense is each country a two-party system?
Model answer
Both have been dominated by two parties that alternate in office, but the USA excludes other parties almost completely while other UK parties win seats and can share in power.
3
Why is the UK described as moving towards a multi-party system?
Model answer
Nationalist and smaller parties win substantial votes and seats, coalition and minority governments have occurred and proportional systems in devolved elections let several parties hold office, while the USA has seen no comparable fragmentation.
4
Besides the electoral system, what practical barriers keep US third parties off the ballot and out of the debates?
Model answer
Ballot access is set state by state and often demands large numbers of verified signatures within tight deadlines, and the presidential debates have a polling threshold that third-party candidates rarely reach, so they struggle to be seen even where they are on the ballot.
5
How do the electoral college and first-past-the-post each squeeze third parties, and why does a UK third party fare better with concentrated support?
Model answer
Almost all states award their electoral votes on a winner-takes-all basis, so a third party can poll widely and still win nothing, whereas a UK party with concentrated regional support converts those votes into seats.
6
How do primaries entrench the two US parties in a way UK selection rules do not?
Model answer
An insurgent movement can capture a major party's nomination from the inside, so it has no incentive to break away and form a separate party as UK factions have sometimes done.
